A step by step tutorial on knitting the i-cord bind off and all the variations you can apply
Are you looking for a very beautiful, neat, and sturdy edge for a garment? Then i-cord bind off is what you are looking for. In this blog post, I’m going to provide you with step-by-step instructions on knitting this currently quite popular cast-off technique.
The i-cord bind off creates a kind of tubular edge that runs horizontally across your last row. I personally feel it looks quite elegant and it’s not even all that hard to do. It does, however, require a bit of patience (it’s somewhat slow to knit) and it’s quite the yarn eater.
The idea behind this bind off technique is quite simple. It’s more or less transferring the basic idea behind a knitting knobby (you know, the little red wooden tubes with the hooks at the top you might have had as a child to produce long cords) to your bind off edge. Of course, you can also knit an icord with double-pointed needles.
So, let’s dive right into it, eh?
Reading tip: Here’s how to knit the i-cord cast-on if you want matching edges.
You knit a standard i-cord by knitting 3 stitches on a double-pointed knitting needle, sliding the stitches back to the right side of the needle without turning the work and continue knitting the right side. The bind off works in a similar way, but requires a bit of preparation to make it work.
Step 1: (Preparation for the actual i-cord) Cast on 3 stitches with a knitted cast on .
Note: You can also use the cable-cast on or a backward loop cast on, but I personally like the knitted cast on most.
Step 2: Knit two standard knit stitches into (two of) the stitches you just cast on.
Step 3: Knit two stitches together through the backloop (that should be one stitch you cast on and one existing stitch of your project you decrease here).
Step 4: You should have three stitches on your right needle now.
Slip those three stitches back to the left needle by inserting the left needle from left to right into these stitches (I am doing it through the back loop on the picture below. But it doesn’t matter if you slip them front or back).
Repeat steps 2-4 until you reach the end of the row and you have three stitches left. (You don’t need to cast on further stitches).
Finish the i-cord bind off by cutting the yarn with a generous 3-4 inches spare, thread the tail into a tapestry needle and weave it through all three stitches left on your needles. Pull tight to secure the i-cord and weave in the ends as you normally would.
You can also knit three together and weave in the tail from there if that’s easier for you.
How much yarn do you need for an i-cord bind off?
This bind off is quite the yarn eater. As a rule of thumb, you should calculate around 13 times as much yarn as your project is wide for a standard i-cord. This factor depends a bit on the material you are using and how tight a knitter you are. I wrote a bit more about the yarn requirements for an icord bind off here.
Variations of the i-cord bind off
Now, I showed you the easiest and most efficient way to knit an I-cord (at least in my opinion). But there are actually many ways to achieve a similar effect. So, I quickly want to talk about these.
#1 Bigger or smaller i-cords
The first variation is quite easy. I showed you the standard i-cord bind off with casting on 3 additional stitches, which will result in a cord that is 2 stitches wide. But you can also go wider or more narrow. In this case, all the steps remain essentially the same, but you
- cast on only 2 stitches or 4 stitches (step 1)
- and then knit 1 or 3 stitches (step 2)
- k2tog tbl and slip 2 or 4 stitches (step 4) back to the left needle.
You can even go for 5 stitches, but if you go wider than that, it won’t look all that pretty anymore.
#2 Binding off with a SSK
Instead of knitting 2 stitches together through the backloop (step 3), you can also do a SSK (slip slip stitch). This will result in a slightly different edge with more pronounced horizontal “V”s.
#3 Mix with a standard bind off
Step 3 is basically nothing but a decrease. So you can have fun with it for different effects. One popular variation goes like this and is somewhat a bit like a normal bind off.
So, instead of k2tog tbl (step 3), you can
- slip one stitch,
- then knit one stitch,
- and then pass the slipped stitch over the knitted stitch.
This can be an option for delicate yarns where knitting through the back loop is a bit more difficult.
#4 Knit through the back loop
Another thing that changes the final outcome is the way you knit the stitches (step 2). I usually just knit them, but you can also knit them through the back loop. This will result in a slightly more condensed edge.
That being said, I do have to mention that the differences between all these versions are so small, that I’m not even sure an experienced knitter will truly be able to see the difference.
Personally, I’d say the only difference that matters is the number of stitches you cast on – the rest is really up to your preferences and what feels more natural to you. Some people have problems knitting through the back loop. In this case, maybe the decrease with the slipped stitches or the SSK alternative might be better for you.
Still, I am a knitter who loves a little testing and that’s essentially why I presented you with all these different alternatives. After all, some small differences can sometimes have a huge impact on the final project.

Why does my I-cord bind off sweater hem roll up toward the sweater?
because it’s probably stockinette stitch upon stockinette stitch..so it curls like mad 😉
How do you knit 2 stitches in three and then slip to other end
I am not sure I understand your question, Janet?
How can curling be prevented on an I-cord cast off hem be prevented?
Could you show how to do the applied i-cord edging please. This is an i-cord added to an already finished project.
I am also wondering if an applied i-cord can be crocheted to a knitted project – that would be interesting. I am mainly a crocheter, I have started to knit as well recently and I keep thinking of ideas to combine these techniques. I absolutely love these crafts and your YouTube channel and website have been so useful and fun too.
I can do that..give me a week or two 🙂
Is it possible to do this as a left-handed person and just mirror everything? or will that have a different effect?
you can just mirror everything!
Love your tutorials!!
