Casting off a loom means securing your finished fabric so it doesn't unravel
When you finish knitting on a loom, the loops on the pegs are still live stitches—they will fall apart if you straightforward pull the fabric off. Casting off (also called binding off) locks each stitch into the next one, creating a finished edge that holds. The method takes about five minutes and uses only the yarn already attached to your work and a loom tool or tapestry needle.
The most common cast-off for looms is the basic over-and-under bind-off, which works on any loom size and any yarn weight. You work around the loom one peg at a time, lifting one loop over another until only a single loop remains. That final loop gets pulled tight and secured.
Key Takeaways
- Casting off locks the live stitches on your loom pegs so the fabric won't unravel when you remove it.
- The basic over-and-under bind-off works on any loom and requires only your yarn and a loom tool or tapestry needle.
- You work around the loom one peg at a time, lifting the lower loop over the upper loop on each peg.
- The process takes about five minutes and leaves a finished edge that is slightly stretchy and durable.
- Common mistakes include pulling too tight (which distorts the edge) and skipping pegs (which leaves live stitches).
Gather your tools before you start
You need three things: your finished loom with stitches still on the pegs, a loom tool (the small hook that came with your loom), and scissors. Some people use a tapestry needle instead of the loom tool—either works, though the loom tool is faster because it is shaped to fit the pegs.
Make sure your yarn is still attached to the fabric. If you have already cut it, you can still cast off, but you will need to thread the tail through a tapestry needle to complete the final steps. Check that all pegs have exactly one loop on them. If a peg is empty or has two loops, fix it before casting off—it is much harder to correct after you have started.
Work the basic over-and-under bind-off around the loom
Start at any peg. Using your loom tool, lift the lower loop on that peg and pull it up and over the upper loop, then off the peg entirely. Now that peg has only one loop left. Move to the next peg clockwise (or counterclockwise—direction does not matter as long as you stay consistent).
On the second peg, you now have two loops: the original loop and the one you just pulled over from the first peg. Lift the lower of these two loops and pull it over the upper loop and off the peg. One loop remains. Repeat this step on every peg around the loom, working in the same direction each time. After you complete one full circle, every peg will have only one loop.
Continue around the loom a second time, using the same over-and-under motion. Each peg still has one loop, and you are pulling that loop over the loop on the next peg. Keep going around until only one loop remains on the entire loom—usually this takes two or three full circles, depending on your loom size.
find the final loop and remove the fabric
When only one loop is left, cut your yarn, leaving a tail about 4 inches long. Thread that tail through the final loop using your loom tool or a tapestry needle. Pull the tail tight so the loop cannot come undone. Weave the tail into the fabric using the tapestry needle, going in and out of nearby stitches for about an inch. This anchors the tail and keeps it from showing on the finished edge.
Now you can remove the fabric from the loom. Gently pull the cast-off edge away from the pegs. The fabric should come free without any loops catching. If a loop does catch, you may have missed a peg during casting off—stop, put the fabric back on the loom, and use your loom tool to lift that loop over the next one before trying again.
Common mistakes that distort the cast-off edge
Pulling too tight is the most common error. If you yank each loop hard as you pull it over, the cast-off edge becomes tight and inelastic, and the fabric may curl or pucker. Instead, pull with steady, even pressure—tight enough that the loop does not slip back, but not so hard that you feel resistance. The edge should look similar in tension to the rows you knitted below it.
Skipping pegs happens when you work too fast and lose track of where you are. If you skip a peg, that loop stays live and will unravel. Count your pegs as you go, especially on your first circle around the loom. Some people mark their starting peg with a stitch marker or a piece of yarn so they know when they have completed one full circle.
Casting off too loosely is less common but still a problem. If your loops are so loose that they slip off the pegs before you pull them over, the edge will be uneven and weak. Practice finding the middle ground: the loop should stay on the peg until you deliberately pull it over.
Variations for different loom types and yarn weights
The basic over-and-under bind-off works on round looms, rectangular looms, and long looms. It also works with any yarn weight, from thin fingering yarn to thick bulky yarn. The only difference is how many circles around the loom you need—thicker yarn may require only one or two circles, while very thin yarn might need three or four.
If you are working with very delicate yarn that breaks easily, use a tapestry needle instead of the loom tool, and move slowly to avoid snagging. If you are working with a very large loom (more than 50 pegs), you may want to cast off in sections rather than all the way around—cast off half the pegs, then the other half, which can be less confusing.
Finishing touches after cast-off
Once the fabric is off the loom and the final tail is woven in, your cast-off edge is complete. If the edge looks uneven or wavy, you can gently block it by laying the fabric flat on a towel, pinning the edges to the desired shape, and letting it dry. Blocking evens out tension and makes the cast-off edge look more professional.
If you notice a loop that did not get cast off and is starting to unravel, stop when ready and use your loom tool to catch that loop and pull it tight. Weave the tail in with a tapestry needle. It is much easier to fix a loose loop right away than to try to repair a run that has traveled down several rows.
Frequently Asked Questions
What if I cast off too tight and the edge is puckered?
You can gently stretch the edge by hand and pin it to the correct width on a blocking board while it dries. If the puckering is severe, you can carefully cut the cast-off edge and re-cast off using the same loops—they will still be live. Use your loom tool to lift each loop back onto a peg, then bind off again with lighter tension.
Can I cast off if I have already removed the fabric from the loom?
Yes, but it is much harder. You will need to use a tapestry needle to lift each loop and pull it over the next one. It is easier to do this if you lay the fabric flat and work on a table rather than holding it in your hands. In the future, always cast off before removing the fabric from the loom.
Do I have to use the over-and-under bind-off, or are there other methods?
The over-and-under bind-off is the most common and works for almost all projects. Other methods exist—like the chain bind-off or the suspended bind-off—but they are more advanced and not necessary for most loom knitting. Start with over-and-under until you are comfortable, then explore other methods if you want a different edge texture.
What happens if I miss a peg and leave a loop live?
That loop will unravel and create a run down the fabric, similar to a dropped stitch. If you notice it right away, put the fabric back on the loom, use your loom tool to lift that loop back onto its peg, and cast it off properly. If the run has already traveled down several rows, you can use a crochet hook to pick up the dropped loop and pull it back up through each row.
How tight should the final loop be when I pull the yarn tail through?
Pull it snug enough that the loop cannot slip back through, but not so tight that you distort the stitch. The final loop should look similar in size to the other stitches on the cast-off edge. If you pull too hard, the edge will pucker; if you pull too loose, the loop may come undone later.
