Loom knitting a sock uses a small circular loom and basic pegs-and-yarn technique

A sock loom is a small circular frame with pegs spaced close together, designed specifically for knitting tubes that fit a foot. You wrap yarn around the pegs in a set pattern, then lift loops over the pegs to create stitches. The process is faster than needle knitting and requires no dropped-stitch recovery—if you make a mistake, you straightforward unwind back a few rows. Most sock looms hold 24 to 48 pegs and produce a finished sock in two to four hours, depending on yarn weight and your speed.

The basic motion repeats: wrap yarn around pegs in order, then use a hook tool to pull the lower loop over the upper loop and off the peg. This creates a knit stitch. You work in rounds, moving up the loom in layers until the sock leg reaches your desired length, then decrease stitches to shape the heel and toe. The yarn never leaves the loom until you bind off the final stitches.

Key Takeaways

  • A sock loom is a circular frame with 24 to 48 pegs; you wrap yarn around them and lift loops over pegs to create stitches in rounds.
  • Sock looms come in different peg counts and spacing—check your yarn weight and desired sock size before buying, as they are not interchangeable.
  • The leg is worked in continuous rounds until it reaches your calf, then you decrease stitches and shape the heel and toe using the same wrapping and lifting motion.
  • Binding off secures the final stitches so the sock does not unravel; the most common method is threading yarn through remaining loops and pulling tight.
  • Loom-knit socks fit most feet without measuring if you use a standard loom size and standard yarn weight, though custom sizing requires adjusting peg count or row height.

Choose a sock loom that matches your yarn weight

Sock looms are sold by peg count and spacing. A 24-peg loom with tight spacing works best for fingering-weight yarn (the thinnest yarn used for socks) and produces a snug fit. A 36-peg or 48-peg loom with wider spacing accommodates sport-weight or worsted-weight yarn and makes a looser, thicker sock. If you buy a loom that is too small for your yarn, the stitches will be tight and hard to lift; too large, and the sock will be baggy and loose.

Most beginners start with a 24-peg loom and fingering-weight yarn because the finished sock is the right thickness for everyday wear and the peg spacing is forgiving. If you already have yarn at home, measure the yarn diameter with a ruler—fingering weight is roughly 1 to 1.5 millimeters thick—and match it to the loom spacing listed on the package or seller's site. Loom brands vary in exact spacing, so do not assume two 24-peg looms are identical.

Set up the loom and cast on

Place the loom on a flat surface with the peg numbers facing you (most looms number the pegs 1 to 24 or 1 to 48 around the circle). Tie a slip knot at the end of your yarn and loop it over peg 1. This is your anchor loop and stays in place throughout the project.

Wrap the yarn clockwise around every peg once, moving from peg 1 to peg 24 (or 48). The yarn should sit in the groove at the top of each peg, not wrapped tightly. When you reach the last peg, wrap around peg 1 again so every peg has one loop. This is called casting on. You now have one layer of yarn on the loom.

Wrap around all pegs a second time in the same direction. Now each peg has two loops—an upper loop (the one you just placed) and a lower loop (the first one you placed). You are ready to start knitting.

Knit the leg in continuous rounds

Pick up the knitting hook (a small crochet-like tool that comes with the loom). Starting at peg 1, insert the hook under the lower loop on that peg. Lift the lower loop up and over the upper loop and off the peg entirely. The upper loop stays on the peg. This is one knit stitch.

Move to peg 2 and repeat: hook the lower loop, lift it over the upper loop, and remove it. Continue around the entire loom, working one peg at a time. When you reach peg 1 again, you have completed one round. The upper loops are now the lower loops for the next round.

Wrap yarn around all pegs again (clockwise, in the same groove). Now each peg has two loops again. Repeat the hooking motion around the entire loom. Each time you complete a round of hooking and wrapping, the sock grows taller by one row. Continue this pattern until the leg reaches your desired length—usually 6 to 8 inches for an adult sock, measured from the cast-on edge to the current row.

Work at a steady pace and keep tension even. If loops slip off pegs, gently push them back into the groove with your finger. If a loop breaks, stop when ready, unwind back to the row before the break, and start that row again.

Decrease stitches and shape the heel

Once the leg is long enough, you will decrease the number of pegs in use to shape the heel. The most common method is skip-peg decreasing: instead of wrapping every peg, you wrap every other peg. This reduces the stitch count by half.

Wrap yarn around pegs 1, 3, 5, 7, and so on (every other peg). Skip pegs 2, 4, 6, and so on. Now only half the pegs have yarn. Hook the lower loop over the upper loop on each peg that has yarn. Wrap every other peg again and repeat the hooking motion. Continue for 2 to 4 rounds, depending on how much shaping you want. The sock will begin to narrow at the heel area.

Some loom patterns call for knit-two-together decreases, where you move loops from one peg to an adjacent peg before hooking. This is more advanced and creates a tighter decrease. For a first sock, skip-peg decreasing is simpler and produces a good fit.

Knit the toe and bind off

After the heel shaping, continue knitting in rounds on the remaining pegs (usually 12 to 24 pegs, depending on your loom size) until the sock reaches your toe. The toe should be roughly 2 to 3 inches long. Then decrease again using the skip-peg method for 2 to 3 rounds until only 4 to 6 pegs have loops.

To bind off, thread a yarn needle (a blunt needle with a large eye) with a 12-inch tail of yarn. Starting at peg 1, insert the needle through the loop on that peg and pull the loop off the peg. Move to peg 2 and thread the needle through that loop, then back through the loop on peg 1 (which is now on the needle). Pull peg 2's loop off the loom. Repeat this motion, threading through the new loop and the previous loop, until all loops are off the loom and threaded onto the needle.

Pull the yarn tail tight to close the toe. Weave the tail through the stitches on the inside of the sock to find it, then trim the excess yarn. Turn the sock right-side out and try it on. The sock is complete.

Common mistakes and how to avoid them

Loops slipping off pegs during wrapping: This happens when you wrap too loosely or bump the loom. Wrap yarn snugly in the groove at the top of each peg, and keep your hands away from the loom while wrapping. If a loop slips, push it back into the groove when ready before continuing.

Uneven tension causing loose or tight stitches: Maintain the same amount of pull on the yarn as you wrap each peg. If some stitches are loose and others tight, the sock will look bumpy and fit poorly. Practice wrapping at a consistent speed and tension on a practice round before starting a real sock.

Forgetting which peg you are on: Use a stitch marker (a small clip or safety pin) to mark peg 1. Move the marker up one peg each round so you always know where you are. This prevents accidentally skipping a peg or hooking the same peg twice.

Binding off too tightly and closing the toe completely: The toe should have a small opening when you pull the yarn tail tight—just enough to fit your foot through. If you pull too hard, the sock will be impossible to put on. Pull the tail snug but not with full force, and test the opening with your fingers before trimming the yarn.

Frequently Asked Questions

How long does it take to loom knit a sock?

A single sock usually takes two to four hours, depending on yarn weight, loom size, and your speed. Fingering-weight yarn on a 24-peg loom is faster because the stitches are smaller and you work fewer rounds. Thicker yarn takes longer because each round requires more wrapping and hooking.

Do I need to knit two socks at once?

No. You can knit one sock, take it off the loom, and knit a second sock later. Many people knit socks one at a time so they can wear the first sock while finishing the second. Some advanced loomers use two looms to knit both socks simultaneously, but this is not necessary for beginners.

What if my sock is too loose or too tight?

Looseness usually means you used a loom that was too large for your yarn, or your wrapping tension was too loose. Tightness means the loom was too small or your tension was too tight. For your next sock, try a different loom size or adjust how firmly you wrap the yarn. You can also adjust fit by changing yarn weight—thinner yarn makes a tighter sock, thicker yarn makes a looser one.

Can I use regular knitting needles to fix a mistake on the loom?

Yes, but only if you are comfortable with needle knitting. If you drop a stitch or notice a hole, you can pick it up with a needle and ladder it back up to the current row. If you are not confident with needles, it is easier to unwind the loom back a few rows and re-knit that section.

What yarn weight should I use for my first sock?

Fingering-weight yarn (also called sock yarn) is the standard choice and works on most 24-peg looms. It produces a sock that is thick enough for daily wear but not bulky. Avoid very thin yarn (lace weight) because it is hard to see and hook, and avoid very thick yarn (bulky weight) because it will not fit on a standard loom.
