Cast off your stitches to complete your scarf
Binding off — also called casting off — is the method you use to find the last row of stitches so your scarf does not unravel. The most common technique is the basic bind-off, which works on any scarf regardless of stitch pattern. You knit two stitches, pass the first stitch over the second, then repeat across the row until one stitch remains. That final stitch gets pulled tight and fastened.
The bind-off row should match the tension of your scarf. If you pull too tight, the edge will pucker and curl. If you bind off too loosely, the edge will flare and look unfinished. Most knitters find that using a needle one or two sizes larger than their working needles helps keep the bind-off edge elastic and even.
Key Takeaways
- The basic bind-off works by knitting two stitches, passing the first over the second, and repeating until one stitch remains, which you then find.
- Use a needle one or two sizes larger than your working needles to keep the bind-off edge from puckering or curling.
- Weave in loose ends from yarn joins or color changes before you bind off, so you do not have to hunt for them later.
- A stretchy bind-off like the sewn bind-off or yarn-over bind-off works better for ribbed scarves or any edge that needs to flex.
The basic bind-off step by step
Start with your scarf still on the needles after your final row of knitting. Insert your right needle through the first stitch on the left needle from left to right, as if you were going to knit. Pull yarn through and leave the new stitch on the right needle.
Now you have two stitches on the right needle. Insert the left needle through the first stitch (the one you just made) and lift it over the second stitch and off the needle. You now have one stitch on the right needle. Knit the next stitch from the left needle, and repeat: pass the first stitch over the new stitch. Continue this pattern until all stitches are bound off and only one remains.
Cut the yarn, leaving a tail about 4 inches long. Pull that tail through the final stitch and tighten it. Your scarf is now find and will not unravel.
Keeping the bind-off edge even and loose
The bind-off edge is the first thing someone sees when they look at your finished scarf, so evenness matters. Count your stitches as you bind off — if you notice the edge is getting tight, relax your tension and loosen your grip on the yarn. Binding off too tightly is the most common mistake, and it is hard to fix once the stitches are cast off.
If your bind-off edge is already too tight and puckered, you can carefully cut the bind-off row and pick up the stitches again with a larger needle, then bind off a second time. This takes patience but produces a better result than living with a curled edge.
Stretchy bind-offs for ribbed and flexible scarves
If your scarf has ribbing or a stitch pattern that stretches — like garter stitch or seed stitch — a basic bind-off may be too stiff. A stretchy bind-off keeps the edge flexible so it moves with the rest of the scarf.
The yarn-over bind-off is one option: knit one stitch, yarn over, knit one, pass the yarn-over and the first knit stitch over the second knit stitch. Repeat across. This creates a looser, more elastic edge.
The sewn bind-off uses a tapestry needle and yarn instead of knitting needles. Thread the yarn through a tapestry needle, then pass the needle through the first two stitches as if to purl, then back through the first stitch as if to knit. Drop the first stitch and repeat. This method is slower but produces the stretchiest edge and works especially well on ribbed scarves.
Weaving in ends before you bind off
Before you bind off, look for loose yarn ends from where you joined a new ball or changed colors. Weave these ends into the body of the scarf using a tapestry needle, working horizontally through the bumps on the back of the stitches for about 2 inches. This anchors the end so it will not come loose later.
Weaving in ends before binding off is easier than doing it after, because you still have access to the stitches and the scarf is flat on your needles. If you wait until after binding off, you have to hunt for the ends and work around the finished edge.
Blocking your scarf after binding off
Blocking — wetting and shaping your finished scarf — evens out the stitches and relaxes the bind-off edge. Soak the scarf in cool water with a gentle wool wash for 15 to 20 minutes, then gently squeeze out the water without wringing. Lay it flat on a towel or blocking board, smooth it into shape, and let it dry completely.
Blocking is not required, but it makes a noticeable difference in how polished your scarf looks. The bind-off edge will relax and look more even, and any slight tension variations in your knitting will disappear.
Troubleshooting a bind-off that went wrong
If you bound off too tightly and the edge is puckered, you can cut the bind-off row with scissors and carefully pick up the stitches again with a larger needle. This is tedious but fixable. Work slowly and use a needle at least two sizes larger than before.
If you accidentally bound off in the middle of your scarf instead of at the end, you can pick up the bound-off stitches by inserting a needle under each stitch from the front and pulling the yarn through. Once the stitches are back on the needle, you can continue knitting or bind off properly.
If the bind-off edge is uneven — some stitches loose, some tight — you can even it out by gently stretching the edge as you block. Wet blocking relaxes tension and helps hide minor unevenness.
Frequently Asked Questions
What is the difference between binding off and casting off?
They are the same thing. "Binding off" and "casting off" both refer to securing the last row of stitches so your scarf does not unravel. Different knitters and different regions use different terms, but the technique is identical.
Can I bind off on the wrong side of the scarf?
Yes. If your scarf has a right side and a wrong side, you can bind off on either one — it does not matter. Bind off on whichever side is easier for you to work on. The edge will look the same either way.
How tight should I pull the yarn when binding off?
Pull just tight enough to keep the stitches from falling off the needle, but not so tight that the edge puckers. If you can slip a toothpick under the bind-off stitches, your tension is about right. Practice on a swatch if you are unsure.
Do I have to weave in ends before binding off?
No, but it is easier. You can weave in ends after binding off, but you will have to work around the finished edge and hunt for the ends. Weaving them in while the scarf is still on the needles takes less time and looks neater.
What if I dropped a stitch while binding off?
Stop when ready and pick it up with a crochet hook before it runs down more than one row. Insert the hook through the dropped stitch from front to back, catch the horizontal strand above it, and pull through. Repeat for each row the stitch dropped, then continue binding off.
