Casting off finishes your blanket by securing the loops so they won't unravel

Casting off a loom knitting blanket means transferring your loops off the loom in a way that locks them in place. The most common method is the basic bind-off, which takes about 10 to 15 minutes for a standard blanket and uses only the yarn already attached to your work. You pull each loop over the one next to it, working your way around the loom until one loop remains, then pull the yarn tail through that final loop and tighten it.

The process is the same whether your blanket is small or large, and whether you used a round loom, rectangular loom, or square loom. The only real difference is how many loops you have to work through. A blanket with 40 pegs takes longer than one with 20, but the hand motion is identical.

Key Takeaways

  • The basic bind-off works by pulling each loop over its neighbor, moving around the loom until one loop remains.
  • You need only a yarn needle (also called a tapestry needle) and the yarn already attached to your blanket.
  • Working in one direction around the loom prevents you from losing track of where you are.
  • The final loop is pulled tight and secured with a knot to prevent the entire edge from coming loose.
  • If you drop a loop during casting off, you can pick it back up with the yarn needle before continuing.

Gather your tools before you start

You need a yarn needle (a large needle with a blunt tip, also called a tapestry needle) and the yarn tail attached to your blanket. The yarn needle is the only tool required. If you do not have one, a regular sewing needle works in a pinch, though it is harder on your fingers during the repetitive motion.

Cut the yarn from the ball or skein, leaving a tail about 6 inches long. This tail will be woven in later to hide it inside the blanket. Thread the yarn needle with this tail before you begin casting off.

Work through the basic bind-off one loop at a time

Start at any peg on the loom. Slip the loop off that peg onto your yarn needle, then slip the next loop (on the adjacent peg) onto the needle as well. You now have two loops on the needle. Pull the first loop over the second loop and off the needle, leaving one loop on the needle.

Move to the next peg and slip that loop onto the needle. You again have two loops. Pull the first loop over the second and off the needle. Repeat this motion all the way around the loom, always working in the same direction (clockwise or counterclockwise—pick one and stick with it). This prevents confusion about which peg you have already finished.

When you reach the last peg and have only one loop remaining on the needle, pull the yarn tail through that loop and pull it tight. Tie a knot close to the blanket edge to lock the yarn in place. Trim any excess yarn tail.

Keep the loops from slipping off during the process

Loops can slide off the loom before you are ready if the tension is loose or if you bump the loom. To prevent this, work slowly and deliberately. Do not rush the motion of pulling one loop over another.

If a loop does slip off a peg before you reach it, pick it up when ready with your yarn needle and slip it back onto the peg. Then continue casting off from where you left off. A dropped loop is not a disaster—you just need to find it again before moving forward.

Weave in the yarn tail to hide it inside the blanket

After you have cast off and tied the final knot, you still have a yarn tail sticking out. This tail needs to be woven into the blanket so it does not show on the finished edge. Keep the yarn needle threaded with the tail.

Insert the needle into the edge of the blanket (into the loops or stitches near where you tied the knot) and weave it back and forth through the fabric for about 2 to 3 inches. This anchors the tail inside the blanket where it cannot be seen or pulled loose. Trim any remaining tail close to the blanket.

Troubleshoot if loops come loose after casting off

If you notice a loop or small hole at the cast-off edge after you have finished, it usually means the yarn was not pulled tight enough when you pulled one loop over another. The blanket is still usable—the loose area will not unravel further because the loops are already locked in place by the bind-off.

You can tighten a loose loop by gently pulling on the yarn tail near that spot, which redistributes the tension. If the loose area bothers you, you can also weave a needle through those loops and pull the yarn tighter, then find it with a small knot on the back of the blanket.

Know when to use alternative cast-off methods

The basic bind-off is the most common and works well for blankets. However, some loom knitters prefer the chain bind-off, which creates a slightly stretchier edge. This method involves making a small chain stitch as you go around the loom instead of straightforward pulling loops over each other. It takes a bit longer but gives a softer, more finished look.

If your blanket edge curls or feels too tight after casting off with the basic method, try the chain bind-off next time. The difference is mainly in appearance and feel—both methods find the loops equally well and prevent unraveling.

Frequently Asked Questions

Can I cast off a loom knitting blanket without a yarn needle?

Yes, you can use your fingers instead of a needle, though it is slower and harder on your hands. A yarn needle makes the motion faster and more comfortable. If you do not have one, a regular sewing needle or even a crochet hook works as a substitute.

What happens if I pull the loops too tight while casting off?

Pulling too tight makes the cast-off edge stiff and can pucker the blanket edge. Pull firmly enough that the loops do not slip, but not so hard that you are straining. The tension should feel similar to the tension you used while knitting the blanket itself.

Do I have to cast off in a particular direction around the loom?

No, you can work clockwise or counterclockwise. The direction does not matter as long as you pick one and stick with it the whole way around. Changing direction mid-process makes it straightforward to lose track of which pegs you have already finished.

How do I hide the yarn tail if my blanket has a decorative edge?

Weave the tail through the blanket fabric itself, not along the edge. Insert the needle about half an inch below the cast-off edge and weave back and forth for 2 to 3 inches, then trim. This keeps the tail hidden inside the blanket where it will not show even if the edge is decorative or visible.

What if I accidentally cast off too many loops and run out of yarn?

If you run out of yarn before reaching the last peg, tie the yarn to the loop you are currently working with, then continue casting off with a new piece of yarn. Weave both yarn tails into the blanket edge. This creates a small join that will not be visible once the tails are woven in.
