Ordinary chain bind off, part 2a: binding off in the middle of a fabric--starting the bind off

8 illustrations Click any illustration to enlarge
A buttonhole, a pocket opening, the bottom of a neck opening: these are all examples of binding off in the middle of a fabric. This sort of binding off often looks very sloppy indeed, both where it starts (at the right edge of the bind off) as well as where it ends (at the left edge of the bind off)

Today's post concerns the starting part of the bind off--the right edge. The next post will be about the ending part of the bind off--at the left edge.

Let's say that our pattern requires us to bind off several stitches in the middle of our fabric, using the chain bind off. (Click here for further information on the basics of the chain bind off). First we'll look at the traditional method, and then the improved method.

The traditional method
Illustration 1, below: Many books do not have any preparation step for binding off in the middle of the fabric. Rather, you are instructed to simply begin with an ordinary chain bind off as illustrated below: the last stitch of the fabric will be the teal stitch, while the first stitch bound off will be the purple stitch, which is being drawn over the green stitch. As you can see, the purple stitch is connected to the teal stitch by the little red tail, and we'll talk more about that little tail in illustrations 3 and 4, below.
Illustration 2, below: According to the traditional method, you are then instructed to continue the bind off as for an ordinary bind off, so the situation looks like this:
Illustration 3, below: As you can see, using the traditional method, the last fabric stitch (teal) and the first bind off stitch (purple) are connected by nothing other than a single strand--the tail yarn which connects the teal stitch to the purple stitch. This little tail (red) is going to form the bottom right corner of the bind off.

Sadly, over time, the result is going to be an ugly and weak gap. As the teal stitch and the purple stitch stretch ever further apart they will stretch and expose that single red tail. In close-up, the situation is going to look like this:
Photograph 4, below: Here it is in real life, in all-purple yarn. The red arrow is pointing to the stretched-out single tail in the lower right corner of the bind off.

The improved method
To get rid of this ugly, weak gap, let's try this trick: instead of starting the bind off with the purple stitch, we'll do a little sleight-of-hand with the teal stitch. Remember that what we want to do is to improve the connection between the last fabric stitch and the first bind off stitch. As it turns out, when we use a kfb increase (knit front, back), the two daughter stitches which result are hooked together by a veritable spider's web of yarn. So, let's turn that fact to our advantage.

(For illustrated instructions on how to work a kfb, click here.)

We'll use a kfb increase and force the teal stitch to do double duty by turning it into the last fabric stitch AND the first bind off stitch. In this manner, we'll be able to position that strong connection between the two stitches just at the weak corner. In other words, in this improved version of the chain bind off, we are going to use the kfb increase to create TWO teal stitches--one to lay in the fabric, and one BONUS stitch, with the strong connection between these two stitches positioned at the weak corner.

Illustration 5, below: Under this new improved method, when we come to knit the teal stitch, we will work it as a kfb into its underlying foundation stitch. As you can see from the illustration below, this results in TWO teal daughter stitches. The kf part of the foundation stitch lays under the first teal stitch, and this part of the foundation stitch is brown, whereas the kb part of the foundation stitch lies under the second teal stitch, and this part of the foundation stitch is orange.Illustration 5, above, shows the very real benefit of using the kfb increase. You see, due to the kfb increase, the two teal stitches are not merely connected by one single tail like ordinary stitches--no! Rather, they are connected by three strands of yarn: the two orange strands in the twisted portion--the kb portion--of the foundation stitch, as well as the one-strand-tail (red) between the two teal stitches themselves, making three strands altogether. So, instead of the single red tail from illustration 3, by the traditional method, we have three strands--two orange and one red--to fortify our corner by this kfb trick. (There is a close-up of this in illustrations 7 and 8, further down this post.)

Per illustration 6, below, we'll begin our improved bind off by drawing the second teal stitch--the bonus stitch which we made--over the purple stitch, then the purple stitch over the green, and so on.Here is something important to remember about the teal bonus stitch: We do not COUNT it as a bound off stitch. Remember: the second teal stitch is an EXTRA stitch which we've created with only one purpose in mind: to put more yarn into that weak right corner of the bind off. Because we created it as an extra stitch, a bonus stitch, we do not count it when we get rid of it again.

In other words, the second teal bonus stitch flashes into existence for only a brief moment: we create it, then draw it over the first stitch to be bound off, and then the bonus stitch is gone forever. It leaves behind only a stronger corner, but it never alters our stitch count. It is only when we draw the purple stitch over the next (green) stitch that we start counting our bound off stitches--the purple stitch, NOT the teal bonus stitch is the FIRST bound off stitch.

Below, illustration 7, is a close up of what the improved corner looks like once we've add the teal kfb bonus stitch. As you can see, the corner which had only a single, weak red tail by the traditional method now has a sturdy spider's web of yarn fortifying the corner in this improved version. Instead of one strand of yarn, three strands of yarn lie there now--the two strands at the top of the bonus stitch's foundation stitch (orange) as well as the bonus stitch's own tail (illustrated in red). This construction will last far longer than the unimproved traditional corner of illustrations 3 and 4.Photograph 8, below: here is what the kfb looks like at the start of a bind off, in real life, in all-purple yarn. Although you can see the extra yarn in illustrations 5, 6 and 7, yet in an actual photograph (8) you can see that all these extra fortifying loops are actually hidden away, and all you see is the front of the bonus stitch. In other words, even though you've packed that formerly weak corner with lots of yarny fortification, the front presents a nice, even appearance instead of the the loose, sloppy and weak single strand in illustration 3 and photograph 4, above.

I think you will find that over time, this little trick of fortifying the right corner of a bind off by starting the bind off with a kfb will pay off in sturdier buttonholes, more robust pocket openings, and easier to pick-up-through neck openings.

One last thing--are you worried that adding an extra stitch to the corner will make the opening too large? In my experience, that won't happen. In fact, the tight twist introduced by the kfb will keep the starting (right) edge of the bind off tighter than by the original method, because you won't have a stretched-out mess in the corner there.

Ordinary chain bind off part 1: binding off along a straight edge

This is the first post of a four-post series on the "chain" or "stitch-over-stitch" bind off, also called "cast off." Today's TECHknitting is about a simple chain bind off along a straight edge. Do you already know how to do this? If so, skip to the bottom where there are three different methods for working the last stitch--methods to help avoid that sloppy last loop. (Also at the bottom are links to the other posts in this series.)

* * *

For today, ordinary stitch-over-stitch bind off along a straight edge--the top of a scarf; the neck of a sweater, for example.

Step 1: Knit a stitch (purple) in the ordinary manner.

Step 2: Knit the next stitch (green) in the ordinary manner. You now have two stitches on your right needle.

Step 3: Insert the left needle into the first (purple) stitch on the right needle.
Step 4: Draw the first (purple) stitch over the second (green).

Step 5. Knit another stitch in the ordinary manner (pink). You will again have two stitches on your needle, just as in step 2. In other words, step 5 is the same as step 2.
Step 6: Continue in this manner, repeating steps 2, 3 and 4 to create a bound off edge as shown below.
There are (at least) three ways to do the last stitch so as to avoid a great big loop at the end.

Method a (below) Work to the end of the row as you have been doing. Draw the second-to-last stitch (blue) over the last stitch (tan), break the tail (orange) short, and thread the end through the last loop as shown. Draw up S-L-O-W-L-Y, feeding as much yarn as possible from the tan loop into the orange tail as you draw the tail up, in order to avoid that big loop at the end.

Method b. (below) Work to the end of the row, but do NOT draw the second-to-last stitch (blue) over the last stitch (tan). Instead, break off the tail (orange) and thread it through BOTH last loops, then draw the tail up. Again, be sure to tighten the orange tail slowly while feeding excess yarn from the last two loops (blue and tan) into the tail, in order to avoid having sloppy last loops.

Method c. (below) Work to within one stitch of the last stitch. Do not knit the last stitch at all. Instead, draw the last (tan) stitch on your left needle up from the row below and draw the second-to-last stitch (blue) over it. In other words, do not knit this last stitch--which is the very edge stitch of your fabric--the "selvedge stitch." Instead, simply pull this (tan) selvedge stitch up, and then draw the second-to-last (blue) stitch over it.

Break off the yarn and draw the tail (orange) of the yarn through the selvedge stitch (tan), as well as the second-to-last stitch (blue). In this illustration the selvedge stitch (tan) is extra-long, because this knitter has been making a chain selvedge all along the fabric edge. However, a chain selvedge is not required to make this kind of ending--any sort of selvedge stitch will do just fine.
Stitch-over-stitch chain bind off has the potential to be tight. If you want a loose bind off, such as at the edge of a scarf or afghan, or at the top of a sock, hat or at a mitten cuff, work this bind off with larger needles than you worked the item knitted. However, sometimes a tight, or at least, a firm, bind-off is wanted, such as at the shoulder seams or the back of the neck of a garment. A firm bind off in these high-stress locations prevents the garment from sagging, stretching and drooping. The stitch-over-stitch bind off is a good match for these situations.

A useful increase: knit into the front, knit into the back of the same stitch

A review of the TECHknitting indexes shows that there are some techniques not yet illustrated, techniques which will be handy on the road ahead.

Here is one such technique. It is called "knit into the front, and then the back of the same stitch," and is sometimes abbreviated
  • k 1 f, b (knit 1 front, back) or
  • k f/b (knit front/back) or simply
  • kfb (knit front back)

As you can guess, knitting twice into the same foundation stitch causes this one foundation stitch give birth to two new daughter stitches, which is how this trick comes to be an increase.

Here is the how-to:

1. (below) This is the "before" picture of the foundation stitch into which you will kfb. In the illustration, the front of the foundation stitch (the right arm, which lays forward on the needle) is blue, while the back of the foundation stitch (the left arm, which lays behind the needle) is green. The running yarn--which will become the first part of the kfb--is pink.


2. (below) The pink running yarn has been knitted in the regular knitting way, and now lays as a loop on the right needle. Note that the foundation stitch (half green and half blue) has not been slid off the left needle. In other words, even though you have already knitted into the foundation stitch, you have only done the first half of the operation (the knitting into the front of the stitch) and therefore, the kfb stitch must remain on the left needle for the second half of the operation.


3. (below) The next step will be to knit into the back arm (the green arm) of the foundation stitch. The red arrow shows the path the needle must take. Specifically, you must swing the needle around to the back of the work, then down through the left arm of the foundation stitch, as shown by the arrow.


4. (below) As you see, swinging the right needle down and through the back (green) arm of the foundation stitch has twisted the foundation stitch into a figure "8," with the right needle through the TOP part of the stitch. Note that the bottom part of the foundation stitch is not twisted, only the top part of the stitch.

Once you have the needle through the top of the foundation loop, the next step is to pull through the running yarn (now colored purple).


5. (below) Here is the finished kfb with the purple running yarn drawn as a loop though the back (green) arm of the foundation stitch.

As you can see, the (pink) stitch through the front (blue) of the foundation stitch is drawn though the untwisted bottom part of the foundation stitch, while the (purple) stitch drawn though the back (green) arm of the foundation stitch is drawn through the twisted top portion of the foundation stitch--the twist having been made back in steps 3 and 4 when the right needle was inserted for the second time into the foundation stitch.


6 and 7. (below) Kfb has a reputation as an amateurish sort of an increase, but this reputation is undeserved. A regular series of kfb's looks very well, as the two final illustrations show.

"My finger hurts from pushing back the left needle tip"

Have you ever given yourself a sore fingertip from pushing back the pointed end of the left knitting needle to bring up the new stitches to be knit? Many knitters use their right forefinger to push back the tip of the left needle (the one with the stitches about to be knit) as a way of delivering fresh stitches to the left needle tip. Some have gone so far as to split the skin of their right forefinger from the repeated jabs.


Even if the problem doesn't extend as far as an actual wound, "pushers" are pretty much prevented from using the really really pointy needles that can make some knitting so much easier (p5tog, anyone?)

So, for all the sore-fingered pushers, here is a little trick: use the barrel of the opposite needle to push back the needle tip. Here's how in three illustrated steps

1. (below) Pinch the right needle firmly (pinch indicated by light brown area)



2. (below) Slide the left needle between the pinching fingers until the tip of the left needle touches the barrel of the right needle.



3. Bracing the left needle tip against the barrel of the right needle, pinch the left needle AND the stitches you want to slide with your left fingers (pinch indicated by light brown area) and push along the needle so the stitches slide towards the left needle tip. The left needle point won't go skidding off the barrel of the right needle, because the right fingers prevent that. Note that the right fingers aren't actually holding the left needle at all--they are only guiding the left needle while pinching the right needle.

Knitting into the stitch below

CAUTION: There are TWO DIFFERENT METHODS SOMETIMES CALLED "KNIT INTO THE STITCH BELOW".  The trick shown here makes a thick, cushy fabric, but is NOT an increase--it does NOT ADD any stitches to the fabric.  The OTHER kind of "knit into the stitch below" is what I call the "nearly invisible increase."  The nearly invisible increase DOES ADD a stitch to the fabric.

It is true that both of of these techniques involve the stitch below, but they are NOT the same thing.  Confusing one for the other will cause no end of problems in trying to follow a pattern!

* * *

4 illustrations, click any illustration to enlarge.
Instructions for various fabric patterns instruct you to "knit into the stitch below." Sometimes, the instructions are a bit more elaborate, stating something like this: "stab the right needle into the stitch below the next stitch on your left needle, knit that stitch, then drop it and the stitch above it off the left needle at the same time."

If this confuses you, you are not alone. Here it is, illustrated:

Step 1: Normally, you would insert the right needle into the blue stitch, because the blue stitch is the next stitch coming up on the left needle. However, to knit into the stitch below, you must locate the stitch BELOW the blue stitch, which is the green stitch in this diagram. Note that it is going to be easier to knit into the green stitch if you get a good grasp of the fabric and stretch it out, which will open the green stitch so that the right needle can be easily inserted along the red arrow path. (If you click on this diagram, it will become much larger, and it will be easier to see all the details.)


Diagram 1 (above) shows a continental knitter (yarn fed on off the left hand) but it matters not which hand feeds the yarn: in this stitch (like every knitting stitch) the path of the yarn through the stitch is the same for continental (left handed feed) and English/throwing style (right handed feed).

Step 2: The right needle has been inserted into the green stitch along the red arrow path of diagram 1, the standing yarn (pink) has been caught on the right needle and the loop of pink yarn, shown pulled through the green stitch, is about to become the newest stitch on the right needle. As you can see, the blue stitch (stitch above) has not yet been released from the left needle. Releasing the blue stitch is the last step in the process, because, by tensioning the blue stitch (stitch above) between the right and left needles while stretching the fabric downward with one or two hands, it is much easier to pull the running yarn (pink) through the green stitch (stitch below).


Diagram 2 (above) above features an English style (throwing) knitter, and the yarn is being fed off the knitter's right hand. Again, the path of the yarn through the stitch is not altered by the hand doing the yarn feed. (If you want to read more about left-handed feed vs. right-handed feed, click here.)

Step 3: The blue stitch (stitch above) has been released and the pink loop is now officially a stitch, sitting on the right hand needle. Note the path of the pink yarn through BOTH the blue AND the green stitches. This is because the blue stitch, which has not been knitted, "runs down" one row until the pink yarn through the green stitch catches it and prevents it from running further.


There are two general uses of this trick. First, it is sometimes used to get rid of a stitch--to park a stitch in the row below and get it out of the way. As an example, in the post of March 3, 2009, TECHknitting applies this technique of "a stitch in the row below" to improve binding off in the round (click here, scroll to third method). 

Another, more common use, is to make fancy, lofty stitch patterns similar to brioche stitches. These sorts of "waffle knits" are cushier than ordinary knits: the technique of knitting into the row below draws up the fabric, making it shorter and thicker, as shown in Illustration 4, below.

This particular stitch pattern is called embossed rib by some and fisherman rib by others, and is made by working back and forth (flat knitting) on an uneven number of stitches, as follows:
  • Purl every other row (that is, rows 1, 3, 5 and so on)
  • On the knit side (rows 2, 4, 6 and so on) *knit 1, then knit into the row below, repeating from * all the way across the row, ending with a knit 1.

Provisional cast on--knitting up vs. knitting down

Back in December '06, TECHknitting featured provisional crocheted cast on. That post promised a future trick to get around a long-standing problem--that there is ALWAYS going to be one fewer loop working down than working up. In October '07, this blog showed another method of provisional cast on: the COWYAK method. In the comments to that post, a reader touched on the same issue, writing...

"When I unzip my provisional cast-on, why are there one fewer stitches going "down" than going "up," AND, what can I do about it?"
Look at your hand. If you are like most people, you have five fingers. But how many spaces do you have between your fingers? For 5 fingers, there are only 4 spaces between your fingers.

The same thing happens in knitting when you work the other way from a provisional cast-on. If you cast on a certain number of stitches and work "up," when you "unzip" the provisional casting on, you'll have one fewer live stitches to knit "down."

In other words, if you provisionally cast on 10 stitches and then undo the cast on, there will only be nine stitches waiting for you to pick up to knit "down." It's not a mystery--it's just the same thing as your fingers--ten stitches knitted "up" leave only nine spaces between them, and that's what you're picking up with the provisional cast-on--the nine spaces.

Of course, the "spaces" analogy is not perfect--we obviously have loops on the needle, not spaces when we catch the live loops from a provisional cast on. However, like the spaces between our fingers, these loops are the bars between the stitches, they are the stitch TAILS, not the actual loops themselves.

Below is a view of what this would look like in real life if you removed the provisional cast-on, took the needles out, and could make the fabric lie flat. See that complicated business on the right and the loop on the left? That's what happens when you pull out the provisional casting-on: The half loops of the rightmost and leftmost tails get pulled upwards to the next row, leaving only the full loops of the tails between the upwards loops: 5 upward loops make 4 downward tails, 9 upward loops make 8 downward tails. In other words, the pattern remains the same: always one fewer downward loops than upward loops.


Now, the upside (har!) is that there are at least two elegant ways to solve this problem. Actually, there is a very good third method which involves an alternative to provisional casting on, and a link will be placed here when that post goes live. For now, however, the two techniques...

TECHnique #1:
Let's say that you want to knit on 8 stitches. Try this trick: provisionally cast on 9 stitches. On the first and second row, knit all 9 stitches. On the third row, knit 2 stitches together (k2tog) where you think they'll be least obvious. In plain stockinette, see if you like the k2tog right in the middle, or if you find an edge less obvious. I vote for the middle of the row, but you must make up your own mind. On the illustration below, the needles and the provisional cast off have been removed, and the fabric has magically been made to lie flat. As you can see, the k2tog is in the middle of the row, picked out for you in green. There were originally 9 stitches cast on and worked "up," leaving 8 tails. However, after the k2tog, there are a matching set of 8 live loops at the top and bottom of this work.


To summarize this technique:
  • Provisionally cast on one extra stitch
  • Row 1 and 2: Knit every stitch going "up"
  • Row 3: Somewhere along the third row, wherever you think it will be least obvious, k2tog to get rid of the extra stitch going "up."
  • Rows 4 and following: knit normally
  • when the time comes to "unzip" the provisional casting on, you will have the correct number of stitches to knit "down."
TECHnique #2:
If the trick of REMOVING an extra stitch going "up" doesn't grab you, here's another alternative which has you ADD an extra stitch going "down."

Provisionally cast on the correct number of stitches, and work all the stitches "up" normally. Unzip the provisional casting on, catch the live loops on your needle, and on the second or third row knitting "DOWN," add a stitch by the "invisible increase" method (click here for instructions).

To summarize this technique:
  • Provisionally cast on the correct number of stitches
  • Knit every stitch going "up"
  • When you come to unzip the provisional casting on, you will find one fewer loops going "down."
  • Pick up the stitches going "down" and knit for two rows.
  • On the third row, add a stitch by making a nearly invisible increase.
Provisional cast on makes a 1/2 stitch discontinuity--a jog-- between where the stitches go "up" and where they go "down."

Not only is there always one fewer stitch going "down" than "up," but the offset between the tails and loops causes another problem, also. Specifically, when we knit "down" on the tail loops, the downward knitting is 1/2 stitch off the upward knitting.

Through an act of heavenly mercy, it turns out that stockinette is so symmetrical that this 1/2 stitch difference is very nearly undetectable in stocking stitch. To prove this is so, take any piece of stockinette fabric, look at it closely, then turn it upside down and look again. You will see that stockinette looks the same upside down and right side up. The only way you'll see the offset in stockinette is at the edge of the fabric, where the 1/2 stitch jog shows as a tiny bump on each side.

Other knit fabrics are not so forgiving. A continuous ribbed fabric would show a 1/2 stitch discontinuity between where the stitches are knit "up" and where the stitches are knit "down." To minimize this, provisional cast on is usually used along a border where the fabric pattern is going to change anyway: the classic location is at the border between the bottom band and the body of a sweater, or at the border between cuff and sleeve. Because the bottom band or cuff is likely to be made in ribbing, while the garment body or sleeve is likely to be made in a different pattern, the discontinuity -- the jog -- of the provisional pick-up line is disguised.


A quick aside: Do you wonder why you'd want to put the cuff on a sleeve via a provisional cast on? There are at least two good reasons to do it: 1. It makes it easy to replace the cuff, important for children's clothing. 2. It makes it easy to adjust the cuff length after the main garment has been knitted and can be tried on. You might want to put the bottom band on a sweater via the provisional cast on method for the same reason: picking up the bottom band and knitting it last would make it easy to adjust the final sweater length after the sweater body has been knit and can be tried on.

If you were making a garment with just one fabric pattern -- a pattern which would look bad with a jog -- you would have to arrange matters so that at the line of the provisional cast on, there would be several rows of plain stockinette stitch.

A common example is lacy scarf worked in a directional lace pattern. Specifically, in order to have the two lace patterns match at the lower ends of the scarf, you might want to start the scarf in the middle with a provisional cast on, and work first towards one end, and then towards the other. However, you might not want the 1/2 stitch jog to interfere with the continuity of your lace pattern. A classic solution is to design the scarf with a stockinette panel, as shown below.

Because the provisional cast on is in the middle of a stockinette fabric, there will be hardly any visible discontinuity where the provisional cast on lies--there will be a 1/2 stitch jog at the edges, but none in the middle of the fabric. Also, the shape of a scarf with a narrow stockinette pattern lies very well on the neck--the narrow bit goes around the back, adding no bulk behind the neck, while the pretty lace panels show in all their glory on the front. The best part about a scarf like this is that the narrow stockinette band has the same number of stitches as the lace panels--no increasing is required. The secret is that lace (pretty nearly any lace) is much wider than a stockinette fabric on the same number of stitches, due to all the yarn overs.

There is a scarf like this somewhere here at Chez TECH, but one of the little TECHlings has it hidden away. When found, a photograph of it will be added to this post...

(Some time later) Oh here it is!

Sigh...

As must be obvious, there is no tech editor at Chez TECHknitting. Accordingly, this blog sometimes gets disorganized. I thought we were heading for garment shaping, I've even knitted up a bunch of samples, but when it came time to write and illustrate all the tricks in the shaping, it turned out that there are still lots of techniques to cover first.

Accordingly, I've axed the previous post with its false promises about socks and garment shaping. Regardless of whatever was stated earlier, this blog simply hasn't progressed as far as garment shaping: not socks, not sweaters, not yet. Instead, for the foreseeable future, TECHknitting will be taking up the old torch again and concentrating on the TECHnique of making knitted fabric.  

Specifically, we'll start tomorrow with a post concerning provisional cast on--what to do about the fact that when you take out the provisional cast on, you'll have 1 less stitch heading "down" than you had heading "up."

Until tomorrow--

Sabbatical

Sabbatical-- Any extended period of leave from one's customary work, esp. for rest, to acquire new skills or training, etc. 

Hi All-I'm still here, but not a lot of blogging is happening (obviously).  The next topic is to be garment shaping, but it's such a large topic that it's hard to tell where to begin.  There have been several false starts, but no approach has yet proved satisfactory.  

In the meanwhile, however, it has been fun working on projects. There's been a knitting drought for several years at ChezTECH as the blog has been all-consuming.  Now it is as if a dam had burst, and I am churning out projects.  It is fun knitting with yarn again, rather than pixels.  

Evidently, TECHknitting is now officially on a sort of a sabbatical break--a substantial period of time off while my thoughts get reorganized and fresh energy is generated to post further.  Sorry to have been incommunicado for so long, but TECHkntting will be back--eventually--and I really hope to tackle garment shaping at that time. 

Thanks for your continued patience, and we'll hopefully meet again in the not-too-distant future.

Goodbye until September...


Dear Readers:

TECHknitting has come to that part of the year when summer travel shuts down the blog. This blog will be on summer vacation until the first week of September -- I am actually leaving the US for over a month, and will have no computer access during this time. (Guess I'll just have to knit -- darn!!)

Before the summer hiatus, however, TECHknitting will undergo its first real housecleaning since its founding. Between now and July 25, all the posts are to be re-examined, new links inserted where needed, and old links updated. Some illustrations will be replaced with corrected versions, and some nagging typos will be corrected. Also, all the indexes will be brought up to date.

If you subscribe to TECHknitting by way of an RSS feed (such as through Bloglines or Google Reader) you may see a flurry of activity that looks like lots of new posts, but this is just false signals being generated by re-posting corrected versions of previous entries. In other words, please ignore any "new post" messages: they are due to this upcoming period of maintenance. No new posts will be forthcoming until September.

Before we part ways for the rest of this summer, dear readers, I thank you for making TECHknitting a stop on your travels through the internet. We'll meet again in September, and when TECHknitting returns with new posts, the first topic will be PICKING UP STITCHES.

Matching 2 pieces of knitting without counting

click any illustration to enlarge
One of the most tedious routines in all of knitting is counting rows or stitches when you have to match two pieces. Is the sweater front as long as the back? Have you knitted both sleeves the same length? Are your two sock tops the same number of rows before the gusset starts? Here is a little trick to avoid all that endless counting and losing track and re-counting. Also, with this trick, you process both pieces at once (twice as fast!)

You will need:
  • a small-gauge circular needle (or two small regular needles or dpn's)
  • some safety pins or bobby pins
TO MATCH ROWS
without counting

In the illustrations below, two pieces of stockinette, one green and one purple, are being matched to make sure they have the same number of rows knitted. The illustrations all show the matching proceeding from right to left--the same way as knitting. However, there is no science to this--you can proceed from left to right just as well.

First, fold both pieces to be matched so that one column from each piece is just at the fold line, then hold the folded pieces pressed together. Pick the plainest possible columns in the work, a column with as few pattern complications as possible--ideal is a column of stockinette stitch in each item.

Per the illustration below, use one point of the circular needle to poke through both arms of the first stitch of the chosen column in the front piece (green), then poke the same needle through both arms of the first stitch of the chosen column in the back piece (purple). The first point (illustrated in black) is fully inserted under the first stitch in the folded column of the green fabric AND the first stitch of the folded column of the purple fabric.
With the second point of the circular needle (illustrated in yellow) poke through the next stitch along the row on the folded column of each piece. As shown below, you now have two needle points poking through two stitches on each of the two pieces of your work.
As shown by the red arrow in the illustration below, the next step will be to remove the black needle and poke it through the third stitch along the folded columns. In other words, you are going to leapfrog the first needle past the second--moving the black needle from the first stitch to the third stitch in the folded column of both pieces.
As shown below, you now again have two needles poking though the work. The reason I prefer a circular needle for matching is because it is harder to drop one needle as you do the leapfrogging part of the trick. However, if you do not have a small-gauge circular needle, small thin regular needles or dpn's will also work well.
As shown below, you continue in this manner, leapfrogging each needle one additional stitch up the folded columns, moving each needle in turn.
When you reach about 15 or 20 rows, run a safety pin (more secure) or a bobby pin (much, much faster) through a matched stitch. There is no particular science to the placement of the pin--the idea is to place pins often enough so that if you DO lose track, you don't have to go very far back to re-start the matching process.

When you get to the top of each column, you will easily see whether your two pieces match--does the last needle inserted go through the top stitch of each column, or does one column extend further? If so, either pull out the excess rows of the longer item, or knit extra rows on the shorter item.

IMHO,
  • Matching is EASIER than counting--in both counting and matching you have to identify the next stitch but counting requires you to keep track the number of stitches, whereas matching does not. Obviously, you CAN count while matching--if you ARE counting, insert pins every 10 or 20 rows exactly to ease your double-check when you re-count--but the point is that with matching, you don't actually NEED to count--"losing count" is no impediment.
  • Matching is FASTER than counting--because you are poking both items at once, it goes twice as fast as counting each item, one at a time.
  • Finally, matching is MORE ACCURATE than counting because you are less likely to make a matching mistake than a counting mistake...
  • matching is mechanical--easier to do in a distracting environment (TV anyone?)
  • even when one needle is moved, the other one is pinning the work, making it harder to lose track
  • placing pins make it easy to go back to double check--simply repeat the "poke-two-columns-at-once" procedure, and make sure all the pins are, in fact, inserted in matching rows of the folded columns
  • matching by this poking method gives you a pointy tool in hand to explore any dubious stitches--helps avoid double counting one stitch or mis-identifying two stitches as one
If you have made beautiful, regular edges (by a chain selvedge or any other method) you can match along the edges, rather than along a folded column. However, experience dictates that in many cases, matching along a column is more accurate than along an edge, and this is especially true if there has been shaping along the edge.

TO MATCH STITCHES
without counting
The above illustrations and instructions show how to match length, row by row. The same procedure also works to match width, stitch by stitch (checking the width of two sleeves as they are increased, for example). Simply fold the two pieces so that there are two adjoining rows, then poke matching stitches along the row to count stitches.

Fully lining hats with polar fleece

click any illustration to enlarge
Lining handknit caps with polar fleece is a good trick to know. (Click here for further information about polar fleece.) Lining with polar fleece can make too-big hats fit, and it eliminates wool itchiness from sensitive foreheads.

TECHknitting blog has already shown how to line knitted hats with polar fleece headband style; today's post shows how to fully line a hat. Basically, with this trick, you make another hat of polar fleece, then sew that inside your knitted hat. With a lining in a heavy weight of fleece, the hat will be suitable for arctic expeditions--excellent where I live (Wisconsin)--but in more temperate climates, you may want to search out a thinner fleece for your lining so the hat won't be impossibly hot.

Step 1 (below): Polar fleece stretches more from selvedge to selvedge than along its length. Cut out a strip from the "wide" way on the fabric (as shown by the "direction of stretch" arrow). The strip should be approximately 10 or 11 inches high and 24 to 26 inches wide. This strip will become the inner lining hat.
Step 2 (below): Wrap the strip around the intended wearer's head with the "not-so-good" side facing out and pin it shut. It would be wise to wear the pinned strip around the house for some time--what seems comfortably snug on first pinning can come to feel ear-numbingly tight after extended wear.
Step 3 (below): Sew the tube shut as pinned. If you have a serger, use that. With a sewing machine you can sew a simple straight seam. If you are sewing by hand, use the back stitch.
Step 4 (below): Trim the excess from the seam. The illustration shows pinking shears, but you can trim with ordinary scissors. Polar fleece does not unravel, so you can trim closer than with woven cloth. An approximately 3/8 inch seam allowance is good, but bold souls can trim as close as 1/4 inch, while nervous sorts can trim to a standard 5/8 seam allowance. If you do have a sewing machine, you might wish to re-sew over the cut edge with the machine's zig-zag or overcast stitch, but this is not necessary.
Step 5 (below): Have the intended wearer try on the tube. Pull the tube down well over the forehead so that you don't accidentally make the lining too shallow. Pin shut the top of the tube so that it comfortably conforms to the shape of the wearer's head. Below is an illustration, and at this link is a photo of the process in real life (Ravelry link).
Step 6: Just as you sewed the back seam of the tube in step 3, so now you will sew the top of the tube shut. Let the actual sewing of the seam be approximately 1/2 inch above the pins, and this should allow plenty of wiggle room.

Step 7: Just as you trimmed the excess from the seam allowance in step 5, so you will trim the excess fabric from above the top seam. Use the same width of seam allowance as on the back of the tube--somewhere between 1/4 inch and 5/8 inch.

Step 8 (below): OPTIONAL Have the wearer try on the sewn-shut tube. At this point, if you like, you can adjust the shape of the tube to be more anatomically correct by flipping up the front of the hat until the tube sits comfortably on the head. Once the comfortable amount of front flip has been determined, mark the flip with a line of pins.
Step 9: If you did step 8, then in this step, you trim away the excess fabric from the front of the lining by trimming along the pinned line. You want to flip up and trim from the front, rather than the back so that you are not cutting through the back seam--cutting the back seam could possibly encourage that sewing in that seam to run out, while cutting in the front creates no problems at all. Remember, polar fleece fabric does not unravel.

Step 10 (below): You have now created a custom lining which will fit the wearer. At this point, you want to sew the lining into the hat. A polar fleece lining is sewn into a hat ONLY AT THE BOTTOM EDGE of the hat. There is no reason to sew it in along the top. By having the lining free-floating in the hat (attached only at the bottom edge) the hat will lay far smoother on the wearer's head than if the lining were attached at the top of the hat too.

Here is the how-to trick for pinning the lining evenly into a hat (or should I say--for pinning the HAT evenly inside the LINING!?)

Begin by turning the hat INSIDE OUT. Fit the lining OVER the hat, with the sewn seams of the
lining facing the inside of the hat. In other words,
  • the hat will be encased, inside-out, inside of the lining
  • the good side of the lining will be showing, and
  • the not-so-good side of the lining (the side with the seams) will rest against the inside fabric of the hat.
Align the back seams.


(If you think you may have seen this diagram before, you have! This is the identical diagram from the post on headband-style lining, and, in fact, the two methods are the same!)

a: Holding the hat (gray shape) inside the lining (blue shape), S-T-R-E-T-C-H the hat and the lining with both forefingers into a long shape which can be stretched no further. This automatically centers the hat inside the lining. Pin the lining to the hat in these two spots.

Do you wonder how you can pin in the lining while your hands are inside the hat and band, stretching everything smooth? You can ask someone to help you, of course, but if you are alone, you can take a shortcut by pinning in one contact point BEFORE you start the stretching-out process, then pinch the hat and lining together where you find the second contact should go. Just be sure not to prick yourself with the pre-set pin, which would go right against one of your stretching fingers.


b. along one side, divide the length between the two pins in half by again stretching the hat and the lining until they can stretch no further. Pin this third contact point.

c. along the other side, repeat step b. Four points are now pinned.

d. again stretching between two contact points, set a fifth contact point at the half-way mark between two already-set pins.

e. repeat the "stretching to find the half-way point" 3 more times until a total of 8 contact points are securely pinned down.

f. the perfectionists among us may want to again halve each side length for a total of 16 contact points.

Do not be alarmed if the lining is larger than the hat OR if the hat is larger than the lining. Once you have sewn the lining in place, the hat and lining will fit one another very well. The larger item, whether hat or lining, is eased to the smaller one by means of stretching out the smaller item as you sew, stitch by stitch, with the pins in place to divide the sections equally so all the ease does not wind up in one big lump on one side of the finished hat.

Thus, a too-large hat can be eased onto a smaller lining by stretching the lining out as the hat is stitched to it. When the sewing is done, the excess fabric of the hat will be distributed in tiny little bite-size pieces all around the lining. As the lining is released from stretching--as it shrinks back to near its original shape--it will take the too-large hat with it. Similarly, hats made of heavily textured fabric (ribbing, cables) will "draw in" much more than the smooth lining. Accordingly, the hat must be gently stretched to fit the lining.

To explain in different words: "Ease as you sew" is sewing jargon for stretching the smaller item (whether hat or lining) to match the larger item (whether lining or hat) as you sew the two together. When you have sewn the garment and the lining together and you take your hand away, you will see that they both lay smoothly together, regardless of the fact that the smaller one has been stitched into a new, stretched position.

As to which stitch to use, you can follow these instructions for the overcast stitch. I highly recommend sewing linings into knit garments by hand, rather than by machine: the end result is nearly always nicer, and the hand-sewn overcast stitch allows for a flexible and comfortable connection between the lining and the hat.
