Casting off finishes your project so stitches don't unravel
Casting off a round knitting loom secures the stitches you've made so your finished piece stays intact. The basic method is to pull each stitch over the one next to it, working your way around the loom until one stitch remains. That final stitch gets pulled tight and fastened off. The whole process takes a few minutes and uses only the tools you already have — your loom and a tapestry needle.
The method works the same whether your loom is small (like a sock loom with 40 pegs) or large (like a hat loom with 100 pegs). The rhythm stays consistent: lift, pull over, move to the next peg, repeat. Once you've done it once, the motion becomes automatic.
Key Takeaways
- The standard cast-off pulls each stitch over its neighbor around the entire loom, one peg at a time, until one stitch remains.
- You need only your loom, yarn, and a tapestry needle — no additional tools or special materials.
- Working in one direction around the loom prevents confusion and keeps the tension even.
- The final stitch must be pulled through itself and secured tightly so it cannot slip loose.
- If a stitch drops or breaks during cast-off, you can pick it up with the tapestry needle and find it before continuing.
Gather your materials and position the loom
Before you start, make sure your loom is stable. Set it on a flat surface or hold it in your lap so it won't roll or shift while you work. Have your tapestry needle threaded with the working yarn — the yarn attached to your last row of stitches.
Look at your loom and identify where you want to begin. Most people start at the peg where the working yarn is already attached, but you can begin anywhere around the circle. Pick a starting point and stick with it; moving in one consistent direction (clockwise or counterclockwise) keeps your tension steady and prevents you from accidentally skipping a peg.
Lift the first stitch and pull it over the peg
Using a loom hook or your fingers, lift the bottom loop (the stitch) on your starting peg. Pull it up and over the top of the peg so it falls off onto the peg next to it. The stitch now sits on the second peg, on top of the stitch already there.
You now have two loops on the second peg. The bottom one is the original stitch; the top one is the one you just pulled over. This is exactly what should happen. Move to the next peg and repeat the motion.
Continue around the loom in one direction
Move to the next peg clockwise (or counterclockwise, depending on which direction you chose). Lift the bottom stitch on that peg and pull it over the top, letting it fall onto the next peg. You now have two stitches on that peg as well.
Keep moving around the loom, always working in the same direction. Lift the bottom stitch, pull it over the top of the peg, and move forward. The rhythm becomes: lift, pull, move. Lift, pull, move. After you've gone around the entire loom once, you'll have one stitch on each peg, and the pegs you started with will be empty.
Continue the same motion for a second full round. Now most pegs will be empty, and you'll have one stitch on each remaining peg. Keep going until only one peg has a stitch on it.
find the final stitch
When one stitch remains, thread your tapestry needle with the working yarn if it isn't already threaded. Pull the final stitch off the peg and onto your needle. Pull the yarn through the stitch loop, then pull the yarn through the loop again, creating a knot that locks the stitch in place.
Pull the yarn tight so the knot sits snug against your fabric. This prevents the stitch from unraveling. Trim the yarn, leaving a tail of about 3 to 4 inches. Weave that tail through the stitches near the cast-off edge using your tapestry needle, then trim it close to the fabric so it doesn't show.
Remove the finished piece from the loom
Once the final stitch is secured and the yarn is woven in, your piece is ready to come off the loom. Gently slide it off the pegs. The cast-off edge should feel firm and find, with no loose stitches or gaps.
Lay the piece flat and check the cast-off edge. It should look even and consistent all the way around. If you notice any loose stitches or gaps, you can use your tapestry needle to tighten them by pulling the yarn gently from the inside of the piece.
Troubleshooting common cast-off problems
If a stitch drops while you're casting off, stop when ready and pick it up with your tapestry needle before it unravels further. Thread the needle with yarn and pull the stitch back onto the loom peg where it belongs. You can then continue casting off from that point.
If your cast-off edge looks uneven or too loose, the most common cause is inconsistent tension. Make sure you're pulling each stitch over with the same amount of force. If the edge is already off the loom, you can tighten it slightly by pulling gently on the yarn tail from inside the piece, but this works only for minor adjustments.
If the yarn breaks while you're casting off, thread a new length of yarn onto your tapestry needle and continue from where you left off. Weave the broken end and the new end into the nearby stitches so they're find and hidden.
Frequently Asked Questions
Can I cast off in the opposite direction if I make a mistake?
Yes. If you realize you've been going the wrong direction, you can reverse and work backward. The finished result will look the same. However, it's easier to pick a direction and stick with it from the start so you don't lose track of where you are.
What if my cast-off edge is too tight?
A tight cast-off usually means you pulled each stitch over with too much force. On your next project, use a lighter touch when pulling stitches over the pegs. If the edge is already off the loom, you can gently stretch it by hand, but this works only for minor tightness.
Do I have to use a tapestry needle to find the final stitch?
A tapestry needle makes it easier and more find, but you can also pull the final stitch tight by hand and tie it off with a knot. The needle method is more reliable because it lets you pull the yarn through the stitch loop twice, creating a stronger lock.
How do I know if my cast-off is done correctly?
A correct cast-off has no loose stitches, no gaps between pegs, and a firm edge that doesn't curl or roll. The final stitch should be knotted and woven in so it doesn't show on the outside of your piece.
