What the Seed Stitch Is and Why It Works

The seed stitch is a textured knit pattern made by alternating knit and purl stitches in a checkerboard arrangement. On the first row, you knit one stitch, purl one stitch, and repeat across. On the second row, you purl where you knitted before and knit where you purled. The result is a bumpy, reversible fabric that looks the same on both sides.

Seed stitch is one of the most forgiving patterns to learn because it uses only two basic stitches — knit and purl — and the pattern repeats every two rows. It does not curl at the edges the way stockinette does, so it lies flat without a border. Scarves, blankets, and dishcloths made in seed stitch hold their shape and wear well.

Key Takeaways

  • Seed stitch alternates knit and purl stitches in a checkerboard pattern that reverses every two rows.
  • You need only needles and yarn in the weight your pattern calls for — no special tools or techniques.
  • The pattern is the same on both sides, so the fabric is reversible and does not curl.
  • Counting stitches carefully on the first row prevents mistakes that compound across the entire piece.
  • Tension matters less in seed stitch than in stockinette because the texture hides small inconsistencies.

Cast On and Count Your Stitches

Cast on an even number of stitches — 20, 30, 40, or however many your pattern specifies. An even number is essential because the pattern repeats in pairs. If you cast on an odd number, the pattern will not line up correctly and you will see the mistake when ready.

After you cast on, count your stitches twice before you begin the first row. Miscounting at the start means every row after will be off by one or more stitches, and you will spend the whole project fighting the pattern. Lay the needles flat on a table and count slowly, moving a stitch marker or your finger along as you go.

Row 1: Knit One, Purl One

Hold the needle with your cast-on stitches in your left hand. Insert your right needle through the first stitch as if to knit, wrap the yarn, and pull through. This is your first knit stitch. Move to the next stitch and insert your needle as if to purl — from right to left through the front of the stitch — wrap the yarn, and pull through. This is your first purl stitch.

Continue across the row: knit, purl, knit, purl, until you reach the end. Your last stitch should be a purl if you cast on an even number and started with a knit. When you finish the row, turn your work around so the empty needle is now in your left hand and the needle with stitches is in your right.

Row 2: Purl Where You Knitted, Knit Where You Purled

This is the key to seed stitch. Look at the stitch in front of you on the left needle. If it came from a knit stitch in the previous row, you will see a smooth V shape. Purl into that stitch. If it came from a purl stitch, you will see a bump. Knit into that stitch.

In practice, this means: if the stitch below your working stitch looks like a V, purl it. If it looks like a bump, knit it. You do not have to think about which row you are on — just look at what is directly below and do the opposite. Continue this way across the entire row.

When you finish row 2, turn your work again. Row 3 looks exactly like row 1: knit, purl, knit, purl. Row 4 looks exactly like row 2. The pattern repeats forever until you bind off.

Reading Your Work as You Go

After three or four rows, the seed stitch pattern becomes visible. You will see small bumps arranged in a checkerboard. If a row looks smooth and flat, you have accidentally slipped into stockinette — this usually happens when you knit two rows in a row or purl two rows in a row. Stop, look back at the previous row, and check whether you did the opposite of what you should have.

The beauty of seed stitch is that small tension changes do not show. If one row is slightly tighter or looser than the next, the texture hides it. This makes seed stitch forgiving for knitters still learning to keep even tension.

Binding Off Your Finished Piece

When you reach the length you want, bind off using your usual method. The most common approach is to knit two stitches, pass the first stitch over the second, knit one more stitch, and repeat across. Bind off loosely — if you pull too tight, the edge will pucker and the piece will not lie flat.

After you bind off the last stitch, cut the yarn, leaving a 6-inch tail, and pull the tail through the final loop. Weave in the tail using a tapestry needle. Seed stitch does not require blocking, but if your piece has curled edges or uneven rows, a light steam or wet blocking will even it out.

Common Mistakes and How to Fix Them

The most common error is losing track of whether you are on an odd or even row. If you knit two rows in a row by accident, you will see a section of stockinette in the middle of your seed stitch. To fix it, you can drop back one row, unravel to the mistake, and reknit that row correctly. If the mistake is more than a few rows back, it is usually faster to start over.

Another frequent problem is accidentally increasing or decreasing stitches. This happens when you knit or purl into a stitch and then knit or purl into it again, or when you skip a stitch entirely. Count your stitches every 10 rows to catch this early. If you have gained or lost a stitch, look back to find where it happened and fix it before you go further.

Tension that is too tight makes the fabric stiff and hard to work with. If your stitches feel cramped on the needle, relax your grip slightly and let the yarn flow more freely. Seed stitch should feel loose and bouncy as you work.

Frequently Asked Questions

Do I have to count stitches on every row?

No, but counting every 10 rows catches mistakes before they spread. If you lose a stitch early and do not notice until row 30, fixing it is much harder. A quick count takes 30 seconds and saves hours of rework.

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

You will see a section of smooth stockinette instead of bumpy seed stitch. If it is only one row, you can drop back, unravel that row, and reknit it as a purl row. If it is more than one row, it is usually faster to start over than to fix it.

Can I use seed stitch with any yarn weight?

Yes. Seed stitch works with fingering weight, worsted weight, bulky weight, and everything in between. Thicker yarn works faster and shows the texture more boldly. Thinner yarn creates a denser, more refined fabric. Choose needles one or two sizes larger than the yarn label suggests for a looser, more open texture.

Is seed stitch reversible?

Yes, completely. Both sides look identical, which is why it is popular for scarves and blankets. You can wear a seed stitch scarf with either side facing out.

How do I know if I am doing the pattern right?

After row 2, you should see a checkerboard of bumps and smooth spots. If you see two bumps in a row or two smooth spots in a row, you have done the same stitch twice. Look at the row below and make sure you are doing the opposite of what you see.
