Knit One, Purl One Creates a Textured Fabric by Alternating Two Stitches

Knit one, purl one means you work one knit stitch, then one purl stitch, then repeat this pattern across your row. The result is a reversible, bumpy fabric called garter stitch when you do it correctly—though many beginners accidentally create something slightly different at first. The pattern is one of the easiest ways to practice switching between knit and purl without losing your rhythm.

This stitch pattern works best on needles sized between US 6 and US 10, with worsted or bulky yarn. Thinner yarn and smaller needles make it harder to see what you are doing. Cast on an even number of stitches—12 to 20 is a good starting point—so your pattern stays balanced across the row.

Key Takeaways

  • Knit one, purl one means alternating a knit stitch with a purl stitch across each row, always starting with a knit stitch on the first row.
  • You must move your yarn to the front of the needle before each purl stitch and to the back before each knit stitch, or your stitches will twist.
  • The pattern creates a bumpy, reversible fabric that looks the same on both sides when done correctly.
  • Counting stitches as you go prevents you from accidentally dropping stitches or adding extra ones when you switch between knit and purl.

How to Work the First Row

Start with your yarn in the back of the needle, behind your working stitches. Insert your right needle through the first stitch on the left needle from left to right, wrap the yarn around, and pull it through to create a knit stitch. Slip the old stitch off the left needle. You now have one knit stitch on your right needle.

Move your yarn to the front of the needle, between the two needles. Insert your right needle through the next stitch from right to left (the opposite direction from a knit stitch), wrap the yarn around, and pull it back through to create a purl stitch. Slip the old stitch off. You now have one knit stitch and one purl stitch on your right needle. Repeat this pattern—yarn in back for knit, yarn in front for purl—until you reach the end of the row. Count your stitches as you finish the row to make sure you still have the same number you started with.

How to Work Subsequent Rows

On the second row, start exactly the same way: yarn in back, knit the first stitch. Then move yarn to front and purl the next stitch. Continue alternating across the entire row. The pattern stays the same on every row—knit one, purl one, knit one, purl one—from the beginning of your project to the end.

After you finish a row, turn your work around so the left needle is now in your left hand and the right needle is in your right hand. The working yarn should be hanging from the last stitch you made. Pull it gently to tighten that stitch, then begin the next row with yarn in back for your first knit stitch.

Common Mistakes That Change Your Pattern

The most frequent error is forgetting to move your yarn between the front and back of the needle. If you purl without bringing the yarn forward first, you create an extra loop on the needle that looks like a twisted stitch. If you knit without moving the yarn back, the same thing happens. Check your yarn position before every stitch—it takes two seconds and prevents hours of unraveling.

A second common mistake is accidentally skipping a stitch or working into the same stitch twice. This happens when you are switching between knit and purl quickly. Slow down on rows 1 through 5. Count aloud if it helps: "Knit, purl, knit, purl." Once your hands learn the rhythm, you can speed up. If you do drop a stitch or add an extra one, the row will have a different number of stitches than you started with. Unravel back to where the count went wrong rather than continuing—fixing it later is much harder.

How to Recognize When You Are Doing It Right

A correctly worked knit one, purl one pattern creates a bumpy, textured surface that looks almost identical on both sides of the fabric. You should see small horizontal bumps across each row, and the fabric should feel slightly spongy when you squeeze it. The edges of your work should be relatively straight, not wavy or bunched up.

If your fabric looks smooth and flat like stockinette stitch (which is all knits), you are accidentally knitting every stitch instead of alternating. If it looks loose and droopy, you may be pulling your yarn too tight when you switch between knit and purl. If one edge is much tighter than the other, you are probably tensioning differently on knit stitches than purl stitches—practice keeping the same gentle pressure on both.

What to Do If You Lose Your Place in the Pattern

If you lose track of whether the next stitch should be a knit or a purl, look at the stitch on the needle in front of you. A knit stitch looks like a small V. A purl stitch looks like a horizontal bump or a little nose. If the stitch below your working needle is a V, you just worked a purl, so the next stitch should be a knit. If it is a bump, you just worked a knit, so the next stitch should be a purl.

You can also count rows. If you are on an even-numbered row and you started with a knit stitch on row 1, you should start this row with a knit stitch too. The pattern repeats exactly the same way on every row, so once you know what row you are on, you know what stitch comes first.

Practice Projects That Use Knit One, Purl One

A dishcloth or washcloth is the ideal first project for this stitch. Cast on 24 stitches and work knit one, purl one for about 30 rows, then bind off. The finished cloth will be roughly square, reversible, and useful. It teaches you to maintain consistent tension and recognize the pattern without the pressure of making something that has to fit a person.

Once you are comfortable, try a scarf. Cast on 18 to 24 stitches and work knit one, purl one until the scarf is as long as you want it—usually 60 to 70 inches. Scarves take longer but are forgiving because they do not have to fit perfectly. You can also practice speeding up your knit and purl stitches without worrying about shaping or stitch counts changing.

Frequently Asked Questions

Do I start with a knit or a purl stitch?

Always start with a knit stitch on the first row. This keeps the pattern balanced. If you cast on an even number of stitches and start with knit, you will end the row with a purl stitch, and the pattern will line up correctly on the next row.

What if I accidentally purl when I should knit?

If you notice the mistake in the same row, unravel back to that stitch and redo it. If you do not notice until the next row, you can either unravel back or keep going—one wrong stitch will not ruin the fabric, though it will create a small bump that breaks the pattern. For practice, it is worth unraveling so you learn to catch mistakes early.

Why does my yarn keep getting tangled between knit and purl stitches?

You are probably not moving your yarn far enough forward or back. When you purl, bring the yarn all the way to the front of the needle, between the needles. When you knit, move it all the way to the back. A clear, deliberate movement prevents the yarn from wrapping around the needle shaft.

Can I use thin yarn for knit one, purl one?

You can, but it is harder to see what you are doing. Worsted weight or bulky yarn shows the bumpy texture clearly and makes it easier to spot mistakes. Once you are comfortable with the stitch on thicker yarn, thin yarn becomes much easier.

Is knit one, purl one the same as ribbing?

No. Ribbing is knit one, purl one worked in the round or on the same side of the fabric every row, which creates vertical lines. Knit one, purl one worked flat (back and forth) creates the bumpy garter stitch texture. The stitches are the same, but the direction and method change the look.
