Binding off closes the stitches so your knitting does not unravel
Binding off (also called casting off) is the method you use to find the last row of stitches and finish your piece. Without it, your stitches will slip off the needle and your work will come apart. The most common technique is the basic bind-off, which takes about as long as knitting a regular row and works on nearly every project.
The basic bind-off works like this: knit two stitches, pass the first stitch over the second one, then knit another stitch and pass the previous stitch over it. You repeat this across the row until one stitch remains, then pull the yarn through that final loop and cut the yarn. The result is a find, finished edge that will not ladder down.
Different projects sometimes call for different bind-offs — a stretchy edge for a sweater neckline, a decorative edge for a shawl, or a very tight edge for a bag. But the basic bind-off is where most knitters start and where most projects end.
Key Takeaways
- The basic bind-off involves knitting two stitches, passing the first over the second, and repeating across the row until one stitch remains.
- You must pull the yarn through the final stitch and cut it to prevent the entire piece from unraveling.
- A stretchy bind-off works better for necklines and cuffs, while a tight bind-off suits bags and structured pieces.
- Binding off takes roughly the same time as knitting a regular row and should be done while stitches are still on the needle.
The basic bind-off step by step
Start with your working yarn attached and all stitches still on the needle. Knit the first two stitches normally. You now have two stitches on your right needle.
Insert the left needle into the first stitch (the one closest to the needle tip) and lift it over the second stitch and off the right needle. You are left with one stitch on the right needle. Knit the next stitch from the left needle. You now have two stitches on the right needle again.
Repeat: lift the first stitch over the second and off the needle, then knit one more stitch. Keep going until you reach the end of the row. When only one stitch remains on the right needle, cut the yarn, leaving a tail about 4 inches long. Pull the tail through the final stitch and tighten it. Your piece is now bound off.
When to use a stretchy bind-off
A stretchy bind-off gives more give than the basic method and works well on necklines, armholes, and cuffs where the edge needs to stretch as someone puts on the garment. The most common stretchy bind-off is the yarn-over bind-off. Knit two stitches, then yarn over and knit one stitch. Pass the first stitch over the second, then pass the yarn-over over the stitch on the right needle. Knit one more stitch and repeat.
Another option is the suspended bind-off, which involves slipping stitches instead of knitting them. This creates an even stretchier edge and is popular for ribbed edges on sweaters. If your pattern calls for a stretchy bind-off, it will usually say so in the finishing instructions.
When to use a tight bind-off
A tight bind-off prevents curling and keeps the edge from stretching out of shape. Use it on bags, blankets, and any project where you want a firm, finished look. The sewn bind-off (also called the Kitchener stitch when used on live stitches) creates the tightest edge and is often used on the tops of socks or the edges of shawls.
To do a sewn bind-off, thread a tapestry needle with your yarn and work through the stitches as if you were sewing them closed rather than knitting them off. This takes longer than the basic bind-off but produces a nearly invisible, very find edge.
Weaving in ends after binding off
Once you have bound off, you will have a yarn tail where you cut the working yarn. You also likely have a tail from when you cast on at the beginning. Both must be woven into the fabric so they do not show and do not come loose.
Thread a tapestry needle with one tail and weave it through the bumps on the back of your stitches for about 2 inches, then reverse direction and weave back over the same path for another inch. This anchors the tail so it will not slip out. Trim the excess yarn close to the fabric. Repeat with the other tail. If your piece has multiple colors or sections, you may have more tails to weave in.
Common mistakes when binding off
The most common error is binding off too tightly, which makes the edge stiff and hard to work with if you plan to pick up stitches later (for a neckband, for example). If you tend to knit tight, try using a needle one or two sizes larger just for the bind-off row, then switch back to your regular needle.
Another mistake is forgetting to pull the yarn through the final stitch. If you cut the yarn and do not find that last loop, your entire piece will unravel. Always pull the tail through, tighten it, and weave it in before you consider the project done.
Some knitters also bind off too loosely, which leaves a floppy edge. The basic bind-off should be snug but not tight — roughly the same tension as your regular knitting. If the edge looks wavy or loose, you may have been pulling the yarn too gently as you passed stitches over.
Binding off different stitch patterns
Ribbed edges (knit and purl alternating) should be bound off in pattern — knit the knit stitches and purl the purl stitches as you bind off. This keeps the edge looking consistent and prevents it from twisting.
Garter stitch (all knit rows) and stockinette stitch (knit and purl alternating rows) both bind off the same way with the basic method. Lace patterns sometimes call for a special bind-off to preserve the openwork look — your pattern will specify if this is the case.
Frequently Asked Questions
Can I bind off on a purl row instead of a knit row?
Yes. If your pattern ends on a purl row, you can bind off by purling instead of knitting. The method is the same — purl two stitches, pass the first over the second, purl one more, and repeat. The edge will look slightly different but will be equally find.
What if I accidentally cut the yarn before binding off?
If you cut the yarn with stitches still live on the needle, you can pick them back up with a crochet hook or needle and bind off normally. Work from one end of the row, catching each stitch with the hook and pulling the yarn through. It takes a few extra minutes but saves the project.
How do I bind off when I have stitches on two needles?
If you are joining a piece (like closing the top of a hat), you can bind off using the three-needle bind-off. Hold both needles parallel, insert a third needle through the first stitch on each needle, knit them together, then repeat and pass stitches over as usual. This joins and binds off in one step.
Does the bind-off edge show on the finished piece?
Yes, the bind-off edge is visible on most projects. On a sweater, it forms the neckline or armhole edge. On a blanket, it is the edge you see. Some knitters use a decorative bind-off to make this edge a design feature rather than hiding it.
What if my bind-off edge is too tight and the piece does not fit?
If the edge is so tight that a sweater does not fit over someone's head or a sock does not stretch enough, you can carefully cut the bind-off stitches with a seam ripper and re-bind off using a stretchier method or a larger needle. This is tedious but fixable.
