How to Cast Off a Rectangular Loom
To cast off a rectangular knitting loom, move each live loop onto the next loop in the fabric’s knitting path, lift the lower loop over the upper loop, and secure the last loop with the yarn tail. This creates a finished edge that will not unravel when the project comes off the loom. The key is to follow the order of the stitches, not simply whichever peg looks closest, especially on a double-knit rectangular loom.
How a Rectangular Loom Cast-Off Works
A cast-off, also called a bind-off or loom knitting takeoff, removes the live loops from the pegs while locking them together in a chain. Each time you combine two loops, one loop becomes part of the finished edge and the other becomes the active loop for the next peg.
A loom cast-off is simply a final row in which the stitches are joined together instead of being left on separate pegs.
Before you start, finish the final knitted row so each working peg has one loop. Do not cut the working yarn yet. Keeping it attached lets you finish at that yarn and fasten the final loop neatly.
You will need:
- Your rectangular loom with the project still on it
- A loom hook or crochet hook
- Scissors
- A yarn needle for weaving in the tail
How to Cast Off a Rectangular Loom
Choose the stitch path that matches the way your fabric was knit. Use this table to match each fabric type with its starting point and next live loop.
| Fabric on the Loom | Where to Start | Which Loop Comes Next |
|---|---|---|
| Single-knit flat panel | The end opposite the working yarn | The next occupied peg along the same row |
| Double-knit rectangular loom fabric | The loop opposite the working yarn’s final position | The next loop in reverse order from the final yarn pass, moving toward the working yarn |
| Separate double-knit layers | One end of one layer | The next live loop on that layer only |
Step 1: Finish the Last Row and Find the Cast-Off Direction
- Knit your final row or stitch-pattern row until every working peg holds one live loop.
- Locate the working yarn. It should be attached to the last loop you made.
- Start at the opposite end of the stitch path so you will finish at the peg holding the working yarn.
For a single-knit panel, the path is usually straightforward: move from one occupied peg to the next across the row. For double knitting, look at the final yarn path around the pegs. Follow that route in reverse toward the working yarn.
Step 2: Join the First Two Live Loops
- Use the loom hook to lift the loop from the first peg.
- Place that loop onto the next peg in the cast-off path, directly above the loop already there.
- Lift the lower loop over the upper loop and off the peg.
The peg should now hold one loop again.
Step 3: Continue Across the Loom
- Move the remaining loop from the peg you just worked onto the next live peg in the stitch path.
- Lift the lower loop over the transferred loop and off the peg.
- Repeat this transfer-and-lift motion until only one live loop remains.
Do not wrap new yarn around the pegs during this process. The loops already on the loom are enough to form the bound edge.
Keep the loops relaxed as you work. Pulling each new loop tight makes the cast-off edge narrower and less flexible than the rest of the project.
Step 4: Secure the Final Loop and Weave In the Tail
- When one loop remains, cut the working yarn, leaving a tail at least 6 inches long.
- Pull the tail through the final loop and snug it just enough to lock the loop in place.
- Thread the tail onto a yarn needle.
- Weave the tail through nearby stitches on the wrong side of the edge, change direction once, and trim the excess yarn.
Your rectangular loom knitting is now fully cast off and ready to remove from the loom.
Cast Off Single- and Double-Knit Rectangular Looms
Cast off single-knit panels across occupied pegs, while double-knit fabric follows the final yarn pass to join or separate its layers.
Single-Knit Flat Panels
A single-knit rectangular loom project has one row of active pegs. This is common for flat scarves, dishcloths, narrow panels, and decorative strips.
Start at the peg farthest from the working yarn. Move the loop to the next occupied peg, lift the lower loop over, and keep traveling across the row. If your pattern uses only part of the loom, ignore unused pegs and move only between pegs holding live stitches.
The finished edge should look like a small chain running across the top of the fabric.
Double-Knit Rectangular Loom Fabric
A double-knit rectangular loom creates two layers of fabric joined along their sides. The live loops may travel from one rail to the other in an alternating or zigzag pattern, depending on how the loom was wrapped.
Follow the order of the final yarn pass rather than casting off one entire rail and then the other at random. The next loop may be directly across the loom, diagonally across a pair of pegs, or farther along the same rail.
This method keeps the layers joined at the cast-off edge, which is usually what you want for a double-knit scarf, panel, or tube.
Leaving Double-Knit Layers Separate
Sometimes you may want an open double-layer edge, such as for a pocket, a lined panel, or an intentional opening.
Cast off the live loops on the first layer in their own stitch sequence, secure that final loop with its yarn tail, then cast off the second layer separately and secure its final loop. Each layer will have its own finished edge rather than one joined edge.
Chunky and Wooden Looms
A chunky loom uses the same cast-off method as a fine-gauge loom. The larger loops can stretch easily, so handle them gently. A crochet hook may be easier to control than a small loom pick if the yarn is very thick.
A wooden rectangular loom also uses the same stitch sequence. Work gently around the peg tops so the hook does not scrape the wood or snag fibers caught near the base of a peg.
Fix Common Loom Cast-Off Problems
Cast-off problems can be corrected by relaxing tight loops, retracing the stitch sequence, restoring slipped loops, and securing the final loop.
The Cast-Off Edge Is Too Tight
A tight edge usually happens when the active loop is pulled snug after every transfer. The loops need enough slack to match the width and flexibility of the knitted fabric.
To correct it, undo a few cast-off stitches by placing each lifted-off loop back on its peg and moving the transferred loop back onto its previous peg. Redo them with a relaxed hand, letting the loop rest naturally on the peg before lifting the lower loop over it. If the full edge is already finished and noticeably puckers, it is usually best to unravel the cast-off chain and redo it.
The Wrong Peg Was Used Next
Using the wrong peg next happens most often on a double-knit rectangular loom. If the edge begins twisting, crossing over itself, or pulling the fabric out of shape, stop before continuing.
Place the active loop back on its previous peg if possible. Then trace the yarn from the last completed row to identify which loop was made next. That next loop, not necessarily the physically nearest peg, is the correct target.
A Loop Slipped Off Before It Was Cast Off
Put the loose loop back on its original peg, keeping it oriented the same way it was before. If the loop has stretched, gently pull the fabric below it to restore its size before continuing the cast-off.
Do not cast off a slipped loop by itself. It must be joined to the previous active loop in the same sequence as the other stitches.
The Last Loop Keeps Loosening
A final loop can loosen unless it is locked in place before the project leaves the loom. If the tail was cut too short, pass a new length of matching yarn through the final loop and secure it, then weave both yarn ends into the wrong-side edge stitches.
Check and Finish the Bound Edge
Before putting the project away, inspect the cast-off edge.
- Every peg should be empty.
- The edge should form one continuous chain without loose live loops.
- The cast-off edge should lie flat without pulling the fabric inward.
- The yarn tail should be locked through the final loop and woven into the wrong side.
- Double-knit fabric should be joined or separated at the edge according to your intended finish.
Gently stretch the edge with your hands. It should move with the fabric rather than feeling like a stiff cord. If the edge is much tighter than the rest of the project, undoing and reworking the cast-off is usually worth the time.
With the final tail woven in, gently shape the edge with your fingers, remove the finished piece from the loom, and enjoy the clean, secure edge you created.
Frequently Asked Questions
What Does Knit Off Mean on a Loom?
Knit off means lifting the lower loop on a peg over the upper loop and completely off the peg. The upper loop remains on the peg as the new live stitch. During a cast-off, you first place one loop onto a peg holding another loop, then knit off the lower loop to join them.
Can I Use a Crochet Hook Instead of a Loom Hook?
Yes, a crochet hook can lift loops over pegs and is often especially useful for chunky yarn. Choose a hook that fits comfortably under the loop without splitting the yarn. The cast-off sequence stays the same: transfer the active loop to the next live peg, then lift the lower loop over it.
How Do I Cast Off on a Hat Loom?
A hat made on a round loom is usually closed at the crown with a gathered finish rather than a flat cast-off. Cut the working yarn, leaving a tail at least 6 inches long, thread it onto a yarn needle, pass it through every live crown loop, remove each loop from its peg, and pull the yarn closed. Pass the tail through the gathered crown again from the inside, weave it into the fabric, and trim it.
Can I Cast Off a Rectangular Loom Scarf the Same Way?
Yes, a rectangular loom scarf uses the same transfer-and-lift cast-off. For single-knit scarves, move across the occupied pegs in order. For double-knit scarves, follow the stitch path created by the final yarn pass so the cast-off edge stays even and the two layers remain properly joined.
