What a long loom is and why it works for blankets

A long loom is a rectangular frame with pegs or nails running along two parallel sides, usually 24 to 60 inches in length. Unlike round looms that create tubes, a long loom produces flat fabric from the start, which is exactly what you need for a blanket. The length of the loom determines how wide your blanket will be — a 48-inch loom gives you roughly a 48-inch-wide finished piece, depending on peg spacing and yarn thickness.

Long looms are faster than hand knitting for blankets because you work with multiple pegs at once, and the repetitive motion is gentler on your hands. You can make a lap blanket in a weekend or a full-size throw in a week or two, depending on yarn weight and how much time you spend at the loom.

Key Takeaways

  • A long loom creates flat blanket fabric directly; you cast on across all pegs, then work row by row without turning the loom.
  • Yarn weight and peg spacing determine blanket texture and drape — thicker yarn on larger pegs makes a looser, airier blanket.
  • The basic stitch is a single knit: pull the old loop over the new one on each peg, working from one end to the other.
  • Binding off takes as long as knitting, so plan your time accordingly and use a tapestry needle to find the final loops.
  • Blocking (stretching and drying flat) evens out tension and makes the finished blanket lie flat and look professional.

Choosing yarn weight and loom size for the blanket you want

Thicker yarn on a long loom with larger pegs produces a blanket faster and with a looser, airier drape. Worsted weight yarn (medium thickness) on a standard loom with pegs spaced about half an inch apart is the most common choice for blankets — it works up quickly without being so loose that the fabric sags. Bulky yarn on a large-peg loom can finish a throw blanket in 10 to 15 hours of actual loom time.

Thinner yarn (sport or DK weight) on a loom with closer peg spacing creates a denser, warmer blanket that takes longer but drapes more elegantly. If you are new to long loom knitting, start with worsted weight and a standard loom; the rhythm is easier to maintain and mistakes are easier to spot.

Measure the finished width you want, then count the pegs on your loom. If your loom has 40 pegs and you want a 40-inch-wide blanket, you will cast on across all 40 pegs. If you want a narrower blanket, you can skip pegs or use only part of the loom.

Casting on and starting the first rows

Casting on for a long loom blanket means looping yarn onto every peg in a single row. Tie a knot at one end of your yarn and loop it onto the first peg. Then wrap the yarn around each peg in order, moving from left to right (or right to left — pick a direction and stick with it). Each peg gets one loop. When you reach the last peg, cut the yarn, leaving a 6-inch tail.

For the first row, tie a new length of yarn to the first peg. Bring the yarn up and around the peg from back to front, then use a loom hook (a small metal or plastic hook) to pull the old loop over the new one and off the peg. The new loop stays on the peg. Move to the next peg and repeat. This is the single knit stitch, and it is the only stitch you need for a basic blanket.

Work slowly on the first few rows while you find your rhythm. The tension should be snug enough that loops do not slip off, but loose enough that you can pull the hook through without forcing it. If loops are falling off, your tension is too loose; if you are straining to pull the hook through, it is too tight.

Working rows and maintaining even tension

After the first row is complete, the new loops are on the pegs and the old loops are gone. For the second row, bring yarn around each peg again and pull the old loop over the new one, just as you did in row one. You are always working the same direction — left to right or right to left — and always pulling the old loop over the new one.

Tension is the biggest factor in how your blanket looks. If some rows are tighter than others, the blanket will have visible ridges. Keep the yarn at the same distance from the pegs on every row, and pull with the same pressure each time. Many people find it helps to anchor the yarn under their thumb or forefinger while working, so the tension stays consistent.

Count your rows as you go, or mark every tenth row with a stitch marker or piece of yarn threaded through the edge. This makes it easier to know when you are close to your target length. A typical lap blanket is 40 to 50 inches long; a throw is 50 to 60 inches.

Binding off so the edge does not unravel

Binding off secures the final row so the blanket does not unravel when you remove it from the loom. On the last row, work the single knit stitch as usual. When you reach the last peg, cut the yarn, leaving a 12-inch tail. Thread the tail onto a tapestry needle (a large, blunt needle used for yarn).

Starting at one end, pull the tapestry needle through the loop on the first peg and slide the loop off. Then pull the needle through the loop on the next peg and slide it off. Continue across the entire row. When you reach the last peg, pull the needle through the final loop twice to lock it, then weave the tail into the edge of the blanket to hide it.

Binding off takes as long as knitting a row, so do not rush it. If a loop slips off before you find it, use the tapestry needle to pick it back up and thread it back onto the loom, then continue.

Removing the blanket and blocking it flat

Once the blanket is bound off, you can slide it off the loom. It will likely have uneven tension in places and may curl at the edges — this is normal. Blocking is the step that makes it look finished.

Fill a sink or bathtub with cool water and add a gentle wool wash (or regular shampoo if you do not have wool wash). Submerge the blanket and let it soak for 15 to 20 minutes without agitating. Drain the water, gently squeeze out excess water without wringing, and rinse in cool water until the water runs clear.

Lay the blanket flat on a clean towel or blocking mat. Gently stretch it to your target dimensions — if you want a 48-by-60-inch blanket, measure and adjust until it is close to that size. Pin the corners and edges to the mat if you have blocking pins, or straightforward smooth it flat and let it dry. This usually takes 24 to 48 hours depending on humidity and yarn weight. Once dry, the blanket will hold its shape.

Troubleshooting common problems

If loops keep falling off the pegs, your tension is too loose or your hook is not catching the loop properly. Slow down and make sure the hook is fully under the old loop before pulling it over the new one. If the blanket is curling at the edges, this usually means the edge pegs are tighter than the middle ones — try loosening your tension slightly on the next blanket, or accept the curl as part of the handmade character.

If you drop a stitch (a loop falls off and you do not notice until later), you can pick it back up with the tapestry needle and thread it back onto the loom, then continue. If you notice a dropped stitch after you have already worked several rows past it, you can ladder it back up: use the tapestry needle to pull the dropped loop up through each row above it, one row at a time, until it is back on the loom.

If a row is noticeably tighter or looser than the ones around it, you can sometimes even it out during blocking by stretching that section more. If the problem is severe, the only real fix is to frog (unravel) back to that row and redo it, which is why maintaining even tension as you go is worth the effort.

Frequently Asked Questions

How long does it take to loom knit a blanket?

A lap blanket in worsted weight takes 15 to 25 hours of actual loom time. A full-size throw takes 30 to 50 hours. Bulky yarn is faster — 10 to 20 hours for a throw. This does not include blocking time, which adds another day or two while the blanket dries.

Can I use any yarn, or does it have to be wool?

You can use acrylic, cotton, wool blends, or pure wool. Acrylic is durable and straightforward to care for. Wool and wool blends block beautifully and hold their shape longer. Cotton is cool and breathable but does not block as dramatically. Choose based on what you want the blanket to do — warmth, durability, or breathability.

What if my blanket comes out lumpy or uneven?

Uneven tension is the most common cause. Blocking helps smooth it out, especially if you stretch the lumpy areas while the blanket is wet. If the problem is severe, you can frog back to the problem row and redo it. For future blankets, focus on keeping the same hand position and pulling pressure on every row.

Do I need a special loom hook, or can I use a regular crochet hook?

A loom hook is designed to fit the peg spacing on your specific loom, so it works best. A small crochet hook (size E or F) can work in a pinch, but it may be too small or too large depending on your loom. A proper loom hook costs $3 to $8 and is worth having.

Can I make a blanket with a pattern, or just solid color?

A long loom works best for solid-color blankets because you are working flat rows. You can change colors between rows to create stripes, or use variegated yarn for subtle color shifts. Complex colorwork patterns are difficult on a long loom and are better suited to hand knitting or round looms.
