Free Infinity Scarf Knitting Pattern (Seed Stitch)

Jump To Pattern

This free infinity scarf knitting pattern is a quick and cozy make, perfect if you want to knit simple scarves without complicated cables or shaping.

The scarf is worked in seed stitch, a beautifully textured fabric created with an easy two-row repeat using just knit and purl stitches.

In some countries, this same stitch pattern is also called moss stitch, but for this pattern, we’ll use the US term: seed stitch.

Using super bulky yarn, this infinity scarf knits up fast and feels wonderfully squishy wrapped around your neck.

You can wear it doubled for extra warmth on chilly days, or draped long as a stylish winter accessory.

Before You Get Started

This infinity scarf is:

  • Skill Level: Advanced Beginner / Easy
  • Knit in the round on circular needles
  • Worked entirely in seed stitch – great practice for switching between knit and purl
  • Made with super bulky yarn, so you only need a few skeins to finish

Because seed stitch alternates knits and purls, it creates a nubbly, balanced fabric that lies flat and doesn’t curl.

That makes it one of the best stitch patterns for scarves, cowls, and the ends of the scarf if you decide to knit it flat and seam later.

This project is beginner-friendly, but it helps if you’re already comfortable with:

  • Casting on
  • Knitting and purling
  • Working in the round
  • Binding off (casting off)
  • Weaving in ends with a tapestry needle

You can easily adjust:

  • The circumference by casting on more or fewer stitches
  • The depth by knitting more or fewer rounds before you bind off

Tools / Materials Needed

Yarn

Check the yardage on your skeins and adjust your purchases if your chosen yarn has more or fewer meters per ball.

Helpful resource: Yarn Weight Guide (+ Conversion Chart)

Needles

The 24″ length is comfortable for knitting this infinity scarf in the round without overstretching the stitches.

Notions

  • Stitch marker – to mark the beginning of the round
  • Additional markers (optional) – if you like to divide the round into sections
  • Tapestry needle – for weaving in ends
  • Scissors
  • Tape measure – to check gauge and finished measurements

Size Info and Gauge

  • Size: Adult (one size)

Finished Measurements (approx.)

  • Circumference: 76 inches / 193 cm
  • Depth (height): 10 inches / 25.5 cm

This gives you a long loop that can be worn:

  • As a single loop with a relaxed drape, or
  • Double wrapped around your neck for extra warmth

Gauge (in the round, seed stitch)

  • 9 sts and 18 rounds = 4″ / 10 cm in seed stitch

The gauge doesn’t have to be perfect for a scarf, but it does affect:

  • The final length of your infinity scarf
  • How many skeins of yarn you will use

If your gauge is very different, you may want to adjust your cast-on stitch count or knit more / fewer rounds in the row repeat section.

Pattern Instructions

Free Seed Stitch Infinity Scarf Knitting Pattern

This infinity scarf is worked in the round using seed stitch throughout.

Note: When you join in the round, make sure the cast-on edge is not twisted around the needle.

Cast On

CO 101 sts.
Place a marker and join in the round, being careful not to twist the stitches.

Seed Stitch Pattern in the Round

Round 1: *K1, P1; rep from * to end of round.
Round 2: *P1, K1; rep from * to end of round.

These two rounds form the seed stitch row repeat.

Work the Scarf

Rep Rounds 1–2 until the work measures 10 inches / 25.5 cm from the cast-on edge, or until your desired depth.

You can try the scarf on as you go by slipping it over your head while the stitches are still on the needles to see how you like the fit.

Bind Off and Finishing

  • Bind off in pattern = as you bind off, knit the knit stitches and purl the purl stitches so the edge blends into the seed stitch fabric.
  • Cut the yarn, leaving a tail.
  • Use a tapestry needle to weave in all yarn ends neatly on the inside of the scarf.

Block lightly, if desired, to even out the stitches, but with super bulky yarn, it often looks great straight off the needles.

To wear the scarf, place the loop over your head, twist once in the middle, and loop it over your head again.

This gives you the classic double-wrapped infinity scarf look.

FAQ

What is the difference between an infinity scarf and a cowl?

Both infinity scarves and cowls are circular pieces with no loose ends, but they have a few differences:

  • Infinity scarf
    • Usually longer in circumference
    • Often worn wrapped twice (or even three times) around the neck
    • Styled more like a traditional scarf that’s been joined at the ends
  • Cowl
    • Typically shorter and closer to the neck
    • Often worn as a single loop
    • Can fit more like a cozy collar or neck warmer

You can also knit a flat scarf in seed stitch and then seam the ends of the scarf together to turn it into an infinity scarf, rather than knitting in the round from the start.

What length should an infinity scarf be?

There isn’t a single “correct” length, but most knit infinity scarf patterns fall in a range that allows for at least one comfortable wrap around your neck:

  • Many infinity scarves are between 50–80 inches (127–203 cm) in circumference.
  • Shorter lengths (~50–60″) usually wrap once or twice for a neater fit.
  • Longer lengths (~60–80″) give a more draped and layered look.

This pattern’s scarf is about 76 inches / 193 cm, which is long enough to comfortably double wrap, especially when knit in a soft, super bulky yarn.

If you want your scarf longer or shorter:

  • Longer infinity scarf: cast on more stitches and/or knit more rounds in the row repeat.
  • Shorter infinity scarf: cast on fewer stitches or knit fewer rounds.

  2. I am excited to try out this scarf! If I use size 10 needles with Lion Brand Acrylic Yarn 545-201 Landscapes Yarn, how many stitches do you suggest I cast on to make it? Thanks!

    Reply

    1. Hello Jessica, You could try casting on 160 sts or 170 sts – but you may need more.
      I can’t say for sure how that will turn out because you will be using a different needle size and yarn weight to what the pattern suggests.
      So you will have to experiment with the cast on number of sts.
      I hope that helps!

  3. This is my first scarf pattern I’m trying! Is this wrapped twice around the neck in the photo?
    How many stitches would I cast on if I wanted to use both skeins of yarn?

    Reply

    1. Hello Elizabeth,
      Yes, the scarf is wrapped around the neck twice in the photographs.
      You will need two skeins to complete the scarf, the cast-on is in the pattern – 101 stitches.
      Thanks,
      Louise

      1. So sorry, the reply button doesn’t work. I stopped at 10 inches but I still have at least half a skein left. I was wondering if I could start over and add more stitches to make it longer to use up all the yarn? Not sure where I went wrong. Thank you!

        1. Hello Elizabeth,
          You could try casting on more stitches if you want the infinity scarf to be longer.
          I haven’t tried that myself but you could try 130+ stitches.
          Or you can knit more so the scarf has a longer length/depth when worn.
          Happy knitting!
