Seed stitch is the simplest textured knit pattern and uses only knit and purl stitches in alternation

Seed stitch creates a bumpy, textured fabric by alternating knit and purl stitches in a checkerboard pattern. On odd-numbered rows, you knit the purl stitches from the previous row and purl the knit stitches. On even-numbered rows, you do the same thing. The result looks like scattered seeds across the fabric, which is where the stitch gets its name.

You do not need any special yarn or needles. Seed stitch works with any weight of yarn and any needle size, though thicker yarn shows the texture more clearly. The pattern is the same whether you are working flat (back and forth on straight needles) or in the round (on circular needles).

Key Takeaways

  • Seed stitch alternates knit and purl stitches on every row, so the stitch you purl becomes the stitch you knit on the next row.
  • Cast on an even number of stitches to keep the pattern balanced across the width of your work.
  • The pattern repeats every two rows, making it straightforward to remember once you understand the basic rule.
  • Seed stitch uses more yarn than stockinette stitch because the purl stitches pull the fabric tighter.

Cast on an even number of stitches to start

Seed stitch requires an even number of stitches on your needle. If you cast on an odd number, the pattern will not balance and you will end up with knit stitches stacked on top of each other instead of alternating with purls.

Cast on using any method you prefer — long-tail, cable, or thumb cast-on all work equally well. The cast-on edge itself does not need to follow the seed stitch pattern. Once you finish casting on your even number of stitches, you are ready to begin Row 1.

Row 1: knit one, purl one across the entire row

On your first row, straightforward alternate: knit one stitch, then purl one stitch, then knit one, then purl one, all the way to the end of the row. Your last stitch will be a purl if you cast on an even number.

As you work, pay attention to which stitch sits on your needle. The stitches on the needle are the ones you will work into. The stitches you just completed are behind them on the fabric.

Row 2: purl the knits and knit the purls

On Row 2, you reverse what you did on Row 1. Every stitch that looks like a knit bump on the fabric gets a purl stitch. Every stitch that looks like a purl valley gets a knit stitch. This is the core rule of seed stitch: you always work the opposite stitch on top of what you see.

If you ended Row 1 with a purl stitch, Row 2 will start with a knit stitch. This keeps the checkerboard pattern balanced. Work all the way across the row, alternating knit and purl as you go.

Repeat Rows 1 and 2 until you reach your desired length

Seed stitch has only two rows in its pattern. Once you have completed Row 2, you straightforward repeat Row 1 again, then Row 2, then Row 1, and so on. The pattern never changes.

Count your rows as you work so you know which row you are on. Many knitters place a stitch marker or write down their row count every 10 rows to avoid losing track. The fabric will look bumpy and textured from the start, so you will know when ready if you have made a mistake — the pattern will look uneven or you will see columns of stitches instead of a checkerboard.

Common mistakes and how to fix them

The most common error is losing track of which row you are on and accidentally knitting two rows in a row or purling two rows in a row. This creates columns of stitches instead of the scattered seed pattern. If you notice this, you can either frog (pull out) back to where the mistake started, or accept it as part of the learning process and continue. The mistake will not unravel your work.

Another frequent mistake is casting on an odd number of stitches. If you do this, the pattern will not balance and you will have a column of knit stitches running down one edge. If you notice this before you have worked many rows, it is worth frogging back to the cast-on and adding one more stitch. If you are already several rows in, you can continue and straightforward accept the unbalanced edge.

Some knitters accidentally slip stitches instead of working them, which breaks the pattern. Make sure you are inserting your needle into each stitch and actually knitting or purling it, not just sliding it from one needle to the other.

Seed stitch in the round requires a different approach

If you are working seed stitch on circular needles (in the round), the pattern changes slightly because you never turn your work. On Round 1, knit one, purl one all the way around. On Round 2, you still knit the purls and purl the knits, but because you are not turning, the stitches line up differently than they do when working flat.

The easiest way to keep track is to place a stitch marker at the beginning of the round and count your rounds the same way you count rows. The fabric will look identical to flat seed stitch once you bind off, but the working process feels slightly different because you are always working from the same direction.

Frequently Asked Questions

Do I need to tension my yarn differently for seed stitch?

No. Seed stitch does not require special tension. If your knit and purl stitches are already even, your seed stitch will look even. If your purls are looser than your knits (a common beginner habit), the purl bumps will look larger. Practice evening out your tension over time, but do not change your technique specifically for seed stitch.

Why does seed stitch use more yarn than stockinette?

Purl stitches pull the yarn tighter than knit stitches, so a fabric with many purls uses more yarn overall. Seed stitch is roughly 50 percent purl, so it uses noticeably more yarn than stockinette (which is all knits on one side). If you are making a garment, add 10 to 15 percent extra yarn to your estimate.

Can I use seed stitch for a whole sweater?

Yes. Seed stitch works for any project — scarves, blankets, sweaters, hats. It is durable and does not curl at the edges like stockinette does. The main drawback is that it uses more yarn and takes longer to knit because you are alternating stitches on every row instead of knitting entire rows.

What happens if I accidentally knit two rows in a row?

You will create a column of knit stitches instead of the alternating pattern. If you catch it when ready, frog back and redo the row. If you do not notice until later, you can continue — the mistake will not cause your work to unravel, though the pattern will look uneven in that spot.
