A scrunchie takes just a few hours and uses yarn scraps you probably have

A knitted scrunchie is a small tube of fabric you slip over a hair elastic. You knit it flat in a rectangle, seam the long edges together, thread the elastic through, and close the ends. The whole project uses less than 50 yards of yarn—perfect for leftover balls—and works on any needles from size 4 to 8. Most people finish one in two to four hours, even if they have only been knitting for a few weeks.

The basic structure is straightforward: cast on 8 to 12 stitches, knit in garter stitch (knit every row) until the piece is long enough to wrap around your hair elastic with a small overlap, bind off, and sew it closed. The only real decision is how thick you want the tube and what yarn weight feels right in your hands.

Key Takeaways

  • A scrunchie is a flat rectangle you knit, fold in half lengthwise, and seam closed to form a tube.
  • Cast on 8 to 12 stitches depending on how wide you want the finished scrunchie, then knit every row in garter stitch until the piece is 7 to 9 inches long.
  • You will need a hair elastic (the kind from a regular ponytail holder), yarn, needles, a tapestry needle, and scissors—nothing else.
  • Garter stitch is the easiest structure for a scrunchie because it lies flat, stretches evenly, and hides mistakes better than stockinette.

What you need to gather before you start

Collect a hair elastic first. A standard elastic from any drugstore works—the kind that comes in a pack of 20. You do not need anything special. Measure it around your finger to know how long your knitted tube needs to be; most are about 2 inches in diameter, so your rectangle should be roughly 6 to 8 inches long when you measure it flat.

For yarn, use anything from worsted weight to bulky. Lighter yarn (fingering or sport weight) will give you a thinner, more delicate scrunchie; heavier yarn makes a thicker, cushier one. You need somewhere between 30 and 50 yards depending on how many stitches you cast on and how long you knit. A leftover ball from another project is ideal.

Needles should match your yarn weight—if the yarn label says size 6 to 8 needles, use size 6, 7, or 8. Straight needles, circular needles, or double-pointed needles all work. You will also need a tapestry needle (the blunt one with a large eye) for seaming, and scissors to cut yarn.

Cast on and choose your stitch count

Cast on 8, 10, or 12 stitches using your preferred cast-on method. Long-tail cast-on and cable cast-on are both reliable. The number you choose determines the width of your finished scrunchie: 8 stitches makes a narrow band about 1 inch wide, 10 stitches makes a medium band about 1.25 inches wide, and 12 stitches makes a wider, cushier scrunchie about 1.5 inches wide.

If you are unsure, start with 10 stitches. It is a comfortable middle ground that works with most yarn weights and looks proportional when wrapped around a standard hair elastic.

Knit in garter stitch until the piece is long enough

Knit every single row. Do not switch to stockinette or any other stitch—garter stitch (knit flat) is the right choice for a scrunchie because it does not curl at the edges, it stretches evenly in both directions, and it is forgiving if your tension wavers.

Keep knitting until your rectangle measures 7 to 9 inches long, depending on the size of your hair elastic. Lay the piece flat on a table next to the elastic and wrap the knitted rectangle around it to check the length. You want a small overlap—about half an inch—so the seam will hold the elastic securely without bunching.

Count your rows as you go if you like, but measuring the length is more reliable. Garter stitch grows slowly, so do not be surprised if you need 50 to 80 rows to reach the right length.

Bind off and prepare to seam

Bind off all stitches using a standard bind-off (knit two stitches, pass the first over the second, repeat until one stitch remains, cut yarn and pull through). This secures the stitches so they do not unravel. Leave a tail of yarn about 6 inches long—you will use this to help close one end of the tube.

Now you have a flat rectangle. Lay it on a table with the right side facing up (or the side you prefer to show). You are about to fold it in half lengthwise and seam the long edges together to form a tube.

Fold and seam the long edges together

Fold the rectangle in half lengthwise so the two long edges meet. The right side of the fabric should face outward if you have a preference. Thread your tapestry needle with a length of yarn (you can use the tail from your bind-off, or cut a new piece about 18 inches long).

Using mattress stitch or a straightforward whip stitch, sew the two long edges together. Mattress stitch is invisible from the outside; whip stitch is simpler if you have never seamed before. Insert the needle under one or two bumps on one edge, then under the corresponding bumps on the other edge, and pull gently. Work your way down the seam, keeping tension even so the tube does not pucker.

When you reach the end, weave the needle through a few stitches on the inside to find the thread, then trim the excess yarn.

Thread the elastic and close both ends

You now have a tube. Thread your hair elastic through the hollow center. If the tube is tight, use the tapestry needle to help guide the elastic through—poke the needle through first, then tie the elastic to the needle eye and pull it through.

Once the elastic is inside, overlap the two open ends of the tube by about half an inch. Using your tapestry needle and a length of yarn, sew the two ends together using a whip stitch or mattress stitch, closing the gap completely. Weave in the yarn tail, trim it, and you are finished.

Frequently Asked Questions

Can I use circular needles or do I need straight needles?

Circular needles work fine. You will still knit flat (back and forth), not in the round. Some knitters prefer circulars for small projects because they are easier to hold and less likely to drop stitches off the ends.

What if my scrunchie is too loose or too tight around the elastic?

If it is too loose, you can tighten the seam by pulling the thread slightly as you sew, or you can unravel and reknit with more stitches. If it is too tight, the elastic will stretch the knitted fabric as you wear it and will loosen over time. Most scrunchies feel snug at first and relax after a few uses.

Do I have to use garter stitch or can I try stockinette?

Stockinette will curl at the edges, which looks messy on a scrunchie. Garter stitch is the standard choice. Once you are comfortable, you can experiment with seed stitch or moss stitch, both of which also lie flat.

How long does a knitted scrunchie last?

A scrunchie made from durable yarn like wool or acrylic will last several months to a year with regular wear. The elastic inside will eventually lose its stretch and can be replaced by carefully opening one seam, sliding out the old elastic, threading in a new one, and resealing.

Can I make a scrunchie from yarn thinner than worsted weight?

Yes. Fingering or sport weight yarn makes a thinner, more delicate scrunchie. You may need to cast on fewer stitches (6 or 8 instead of 10 or 12) to keep the proportions balanced, and you will need to knit more rows to reach the same length.
