Casting off closes your stitches so they won't unravel when you remove the finished piece

Casting off (also called binding off) is the final step that secures the loops on your loom so your knitted fabric stays intact. The basic method works the same way on most looms: you lift one stitch over another to lock them in place, working around the loom until all stitches are gone. The result is a finished edge that looks neat and holds firm.

The exact steps depend on whether you're using a round loom, rectangular loom, or long straight pegs, but the principle stays the same. You'll need your knitting tool (the hook or pick that came with your loom) and about five minutes for a small project. Most cast-offs create a slightly tighter edge than the rest of your fabric, which is normal and actually helps prevent stretching.

Key Takeaways

  • The standard cast-off lifts one stitch over the next, working your way around the entire loom until no stitches remain.
  • You must complete all rows of knitting before you cast off—stopping mid-project and casting off early will leave you with an incomplete piece.
  • The cast-off edge will be slightly tighter and thicker than the rest of your fabric, which is expected and prevents unraveling.
  • Casting off takes only a few minutes once you understand the motion, and the same technique works across different loom sizes and shapes.

The standard cast-off for round and rectangular looms

Start by making sure you have completed your last row of knitting. All pegs should have exactly one loop on them. Insert your knitting tool through the first stitch (the loop on the first peg), then through the second stitch on the next peg. Lift the first stitch up and over the second stitch, letting it drop off the peg. You now have one loop remaining on that second peg.

Move to the next peg clockwise (on a round loom) or to the right (on a rectangular loom). Insert your tool through the loop currently on that peg, then through the loop on the peg after it. Lift the first loop over the second and drop it off. Continue this pattern all the way around the loom. When you reach the last peg, you'll have one final loop left. Pull your yarn through this loop, tighten it, and cut the yarn about 4 inches from the loom. Pull the tail through the loop to find it.

Casting off on long straight pegs or rake looms

Long straight looms (sometimes called rake looms or straight-peg looms) cast off the same way, but you work in a line rather than in a circle. Begin at one end of the loom with your first stitch. Insert your tool through the first loop, then through the second loop on the next peg. Lift the first loop over the second and drop it off the peg.

Move along the row, repeating this lift-and-drop motion peg by peg until you reach the end. Your last remaining loop should be at the final peg. Pull the yarn tail through this loop, tighten, and cut about 4 inches from the loom. Thread the tail through the loop one more time to lock it in place. This creates a finished edge that won't unravel even if you tug on it.

Keeping tension even while casting off

The most common mistake is pulling too hard on the yarn as you cast off, which makes the edge tight and bunched. Instead, keep the same gentle tension you used while knitting. The stitches should slide smoothly over each other without resistance. If you feel yourself straining, you're pulling too tight—ease up and let the yarn flow naturally.

Another mistake is skipping pegs or working out of order, which leaves loops behind that unravel later. Count your pegs before you start and work methodically from one end to the other (or all the way around on a circular loom). If you accidentally drop a stitch or miss a peg, stop, pick up that loop with your tool, and continue from where you left off. It's easier to fix a mistake mid-cast-off than to discover loose stitches after you've removed the piece from the loom.

What to do if your cast-off edge looks uneven

An uneven cast-off edge usually means your tension changed partway through—you pulled tighter on some stitches than others. This is purely cosmetic and won't affect how your finished piece wears. If the edge bothers you, you can hide it by seaming it to another piece, folding it under as a hem, or straightforward wearing the piece in a way that doesn't show the edge.

If your cast-off edge is so tight it's puckering the fabric, you pulled too hard while casting off. On your next project, practice keeping your hand relaxed and letting the yarn move freely. If your edge is too loose and stitches are slipping, you didn't pull the yarn tight enough when you finished. The tail should be snug through that final loop, but not so tight you can't move it by hand.

Removing your finished piece from the loom

Once you've cast off and secured the final tail, your piece is ready to come off the loom. Gently slide each peg out of its loop, working your way around (or along the row). The cast-off edge will hold everything together, so you won't lose stitches as you remove the pegs. Take your time and support the fabric with your other hand so it doesn't fall or stretch.

After removal, you can weave in any loose yarn tails using a yarn needle. If your pattern called for a seam, you'll do that now. Otherwise, your piece is finished and ready to wear or gift. The cast-off edge will soften slightly after a gentle wash and will blend in better with the rest of the fabric over time.

Frequently Asked Questions

Can I cast off if I haven't finished all my rows?

No—casting off before you've completed your pattern will leave you with an incomplete piece. If you need to stop knitting before you're done, straightforward leave the stitches on the loom and come back to it later. The loops will stay in place as long as the pegs are occupied.

What if I accidentally cast off too tight and my edge is puckered?

The puckering is permanent once cast off, but it won't affect how the piece wears. You can hide it by seaming it to another piece, folding it under, or positioning it where it won't show. On your next project, practice keeping your hand relaxed while casting off.

Do I have to cut the yarn after casting off?

Yes, you need to cut the yarn and pull the tail through the final loop to lock it. Without this step, the last stitch can unravel. Leave about 4 inches of tail so you have enough to weave in later or tie off if needed.

Can I use the same cast-off method on every type of loom?

Yes, the basic lift-and-drop method works on round looms, rectangular looms, and straight-peg looms. The only difference is the direction you work (around a circle, across a rectangle, or along a line), but the actual motion of lifting one stitch over another stays the same.
