Moss stitch is a two-row pattern that alternates knit and purl stitches

Moss stitch (also called seed stitch in some patterns) creates a bumpy, textured fabric by switching between knit and purl stitches in a deliberate pattern. On odd-numbered rows, you knit the stitches that appear as purls and purl the stitches that appear as knits. On even-numbered rows, you do the exact opposite. The result is a reversible fabric with the same texture on both sides, which makes it useful for scarves, blankets, and garment edges.

The pattern repeats every two rows, so once you understand the basic sequence, you can work it continuously without consulting a chart. Moss stitch works on any number of stitches and requires only the two basic stitches you already know.

Key Takeaways

  • Moss stitch alternates knit and purl stitches in a specific pattern that changes every row.
  • Row 1: knit one, purl one, repeat across; Row 2: purl one, knit one, repeat across.
  • The pattern is reversible, so both sides of the fabric look identical.
  • Moss stitch works on any cast-on number and requires no special tools or techniques.

The two-row repeat pattern explained

Moss stitch follows a straightforward two-row cycle. On Row 1, you knit one stitch, then purl one stitch, then knit one, then purl one, continuing this pattern all the way across your needles. On Row 2, you reverse it: purl one stitch, then knit one stitch, then purl one, then knit one, all the way across.

The key is that you are always working the opposite stitch from what you see on the needle. If the stitch below your working yarn looks like a V (a knit stitch), you purl it. If it looks like a horizontal bump (a purl stitch), you knit it. This is why the pattern creates that characteristic bumpy texture—the stitches are constantly switching direction.

Once you finish Row 2, you go back to Row 1 and repeat. You never have to memorize more than two rows, and the pattern stays the same for the entire project.

How to work Row 1: knit one, purl one

Cast on an even number of stitches—20, 30, 40, or any multiple of 2 will work. If you cast on an odd number, the pattern will still work, but the edges will look slightly different.

Hold your needles with the working yarn in back. Insert your right needle through the first stitch on the left needle from left to right, wrap the yarn around, and pull through to create a knit stitch. Now bring your yarn to the front of your work. Insert your right needle through the next stitch from right to left (the purl direction), wrap the yarn around, and pull through to create a purl stitch. Bring your yarn back to the rear of your work. Knit the next stitch. Bring your yarn forward again and purl the next stitch. Continue this pattern—knit, purl, knit, purl—until you reach the end of the row.

When you finish Row 1, you will have a row of alternating knit and purl bumps. Turn your work around so the other needle is now in your right hand, ready to begin Row 2.

How to work Row 2: purl one, knit one

Row 2 is the reverse of Row 1. Bring your yarn to the front of your work. Insert your right needle through the first stitch from right to left and purl it. Now bring your yarn to the back. Insert your right needle through the next stitch from left to right and knit it. Bring your yarn forward and purl the next stitch. Bring your yarn back and knit the next stitch. Continue purl, knit, purl, knit across the entire row.

When you finish Row 2, you will see the bumpy texture starting to form. The stitches from Row 1 are now sitting on top of the stitches from Row 2, creating that characteristic seed-like appearance. Turn your work and go back to Row 1. Repeat these two rows for as long as your project requires.

Why the yarn position matters

Moving your yarn between the front and back of your work is not just a habit—it is essential to moss stitch. When your yarn is in back, you can knit. When your yarn is in front, you can purl. If your yarn is in the wrong position, you will accidentally create a yarn over (an unintended hole) instead of the stitch you intended.

Develop the habit of moving your yarn deliberately before each stitch. Some knitters find it helpful to say "yarn back, knit" and "yarn forward, purl" out loud as they work, at least until the motion becomes automatic. This small discipline prevents mistakes that would otherwise require you to unravel several rows.

Common mistakes and how to fix them

The most frequent error is forgetting to move your yarn between stitches. If you knit a stitch with your yarn in front, or purl a stitch with your yarn in back, you create a yarn over—a small hole in your fabric. These are visible and will disrupt the texture. If you notice one when ready, you can usually drop back one row and fix it. If you do not notice until several rows later, you may need to unravel back to that point.

Another common mistake is losing track of which row you are on. Because the pattern repeats every two rows, it is straightforward to accidentally work Row 1 twice in a row, which breaks the pattern. Some knitters place a stitch marker at the beginning of each row, or use a row counter to keep track. Others straightforward glance at the fabric: if the bumps look aligned and even, you are on track. If they look chaotic, you have probably worked the wrong row.

If you accidentally purl when you should have knitted (or vice versa), the stitch will look wrong when ready. You can usually catch this before moving to the next stitch and straightforward redo it. Do not be afraid to pull out a stitch or two—it is much faster than unraveling an entire row.

Moss stitch in different projects

Moss stitch works well for scarves because it is reversible and has good drape. It also lies flat, so it does not curl at the edges the way stockinette stitch does. For this reason, many knitters use moss stitch for the borders of garments—around the neckline, cuffs, and hem—to frame the main stitch pattern and prevent curling.

Blankets and dishcloths made in moss stitch are durable and absorbent. The texture grabs water well, making it practical for kitchen use. Because moss stitch is dense, it uses more yarn than stockinette stitch of the same dimensions, so plan accordingly if you are substituting it into a pattern designed for a different stitch.

Moss stitch also works as an all-over fabric for sweaters, though it will be thicker and less stretchy than stockinette. If you are adapting a pattern, you may need to cast on fewer stitches to achieve the same finished width, because moss stitch tends to be denser.

Frequently Asked Questions

What is the difference between moss stitch and seed stitch?

Moss stitch and seed stitch are often used interchangeably, but some patterns distinguish them. True seed stitch works the same way on every row: knit one, purl one, repeat. Moss stitch (as described here) alternates the pattern every row. Both create a bumpy texture, but seed stitch requires you to remember which stitches are which, while moss stitch is easier because you straightforward reverse the previous row. Check your pattern to see which one is called for.

Can I use moss stitch on an odd number of stitches?

Yes. If you cast on an odd number, the pattern still works, but your edges will not be perfectly symmetrical. The first and last stitch of each row will be different, which can create a slightly uneven selvage. For most projects this is not noticeable, but if edge appearance matters, cast on an even number.

Does moss stitch use more yarn than other stitches?

Moss stitch is denser than stockinette stitch because the constant switching between knit and purl creates a tighter fabric. This means it uses slightly more yarn for the same dimensions. If you are substituting moss stitch into a pattern designed for stockinette, you may run short. Weigh your yarn before starting to make sure you have enough.

How do I know if I am working the pattern correctly?

Look at the fabric as you work. Moss stitch should show a regular pattern of small bumps, with no obvious rows or columns. If you see horizontal lines or if the bumps look random, you have probably worked the wrong row or made a stitch error. The texture should look the same on both sides of the fabric.

What happens if I accidentally work the same row twice?

You will break the pattern and create a visible line in the fabric. The bumps will look misaligned on one side of that row. If you catch it when ready, pull out the extra row and redo it. If you do not notice until later, you can either unravel back to the mistake or accept it as part of the handmade character of the piece.
