The Knit and Purl Are Opposite Motions With the Same Needle

The knit stitch and purl stitch are the foundation of nearly every knitting pattern. A knit stitch pulls yarn through a loop from back to front; a purl stitch pulls yarn through from front to back. The difference is small — one motion — but it changes how the fabric looks and feels. Most patterns use both stitches in combination to create texture, color, and structure.

You do not need to master both at once. Many knitters learn the knit stitch first, make a straightforward scarf or dishcloth in knit only, and then add purl once they feel steady with the needle. Both stitches use the same needles, yarn, and basic hand position. The only thing that changes is where the yarn sits before you insert the needle.

Key Takeaways

  • The knit stitch pulls yarn from back to front through the loop on your needle; the purl stitch pulls it from front to back — the motions are mirror images.
  • Both stitches start the same way: you insert the needle through the loop, wrap yarn around the needle, and pull a new loop through.
  • Tension — how tightly you hold the yarn — matters more than speed; loose, even stitches look better than tight, uneven ones.
  • Alternating knit and purl rows creates a bumpy texture called garter stitch; knitting one side and purling the other creates smooth stockinette stitch.

How to Do the Knit Stitch Step by Step

Start with yarn on the back side of your work (the side facing away from you). Hold the needle with stitches in your left hand and the empty needle in your right. Insert the right needle through the first loop on the left needle from left to right, going in from the front.

Wrap the yarn around the right needle, moving it from back to front and then under the needle. Pull the right needle back through the loop, bringing the new loop with it. Slip the old loop off the left needle. You now have one knit stitch on the right needle. Repeat this motion for every stitch across the row.

The most common mistake is pulling the yarn too tight as you wrap it. Tight stitches are hard to work into on the next row and make your fabric stiff. Let the yarn sit loosely around the needle before you pull through. Your stitches should slide easily along the needle shaft.

How to Do the Purl Stitch Step by Step

Start with yarn on the front side of your work (the side facing you). Hold the needles the same way as the knit stitch. Insert the right needle through the first loop on the left needle from right to left, going in from the back.

Wrap the yarn around the right needle, moving it from front to back and then under the needle. Pull the right needle back through the loop, bringing the new loop with it. Slip the old loop off the left needle. You now have one purl stitch on the right needle. Repeat for every stitch across the row.

The purl stitch feels awkward at first because the yarn is in front of you and the needle motion is reversed. Many knitters hold the yarn differently for purl — some keep it in the same hand position and let it sit in front, others move their hand forward. Experiment to find what feels natural. Speed comes later; accuracy comes first.

Why Yarn Position Changes Everything

The only real difference between knit and purl is where the yarn sits before you insert the needle. In a knit stitch, yarn stays in back. In a purl stitch, yarn moves to the front. This position determines which direction the loop forms and which side of the fabric shows the bump.

When you knit, the bumps form on the back of your work. When you purl, the bumps form on the front. This is why alternating knit and purl rows creates different textures. If you knit every row, the bumps show on alternating sides, creating a textured look. If you knit one row and purl the next, the bumps stay hidden on the inside, creating a smooth, flat fabric.

Common Stitch Patterns Using Knit and Purl

Garter stitch is knit every row, or purl every row. Both produce the same bumpy, reversible texture. Garter stitch is thick, warm, and forgiving — it hides tension mistakes and works well for blankets, scarves, and dishcloths.

Stockinette stitch alternates knit rows with purl rows. One side is smooth and V-shaped (the knit side); the other is bumpy (the purl side). Stockinette is the most common stitch in sweaters, hats, and fitted garments because it drapes well and shows stitch definition.

Ribbed stitch alternates knit and purl stitches within the same row — for example, knit one, purl one, knit one, purl one across. Ribbing is stretchy and clings to the body, so it appears on cuffs, collars, and waistbands. Ribbing also helps edges stay flat and prevents curling.

Seed stitch alternates knit and purl stitches in a checkerboard pattern: knit one, purl one on the first row; purl one, knit one on the second row. Seed stitch is bumpy on both sides and does not curl, making it popular for blankets and scarves where both sides show.

How to Fix Dropped Stitches and Tension Problems

A dropped stitch happens when a loop slides off the needle. If you notice it right away, insert the needle back through the loop from front to back and pull the working yarn through. If the stitch has dropped several rows, use a crochet hook to pull the yarn back up through each row, one at a time, working from bottom to top.

Tension problems show up as stitches that are too loose or too tight. Loose stitches happen when you wrap yarn too loosely or pull too gently. Tight stitches happen when you pull too hard or hold the yarn too close to the needle. The fix is the same: slow down and pay attention to how much force you use. Even tension matters more than speed.

If your first few rows look messy, that is normal. Your hands are learning a new motion, and muscle memory takes time. Most knitters find their rhythm by row ten or fifteen. If tension stays uneven after that, try holding the yarn in a different way — some people hold it over the index finger, others under it, and some wrap it around multiple fingers. The "right" way is whatever keeps your tension even.

Frequently Asked Questions

What is the difference between knit and purl if they use the same needles?

The needles are identical. The difference is where the yarn sits before you insert the needle. Knit keeps yarn in back; purl brings yarn to the front. This changes which direction the loop forms and which side of the fabric shows the texture.

Do I have to learn purl if I only want to make garter stitch?

No. Garter stitch uses only knit stitches (or only purl stitches), so you can make scarves, blankets, and dishcloths knowing just one stitch. However, most patterns beyond beginner level use both knit and purl, so learning purl opens up more options.

Why do my stitches look loose and uneven?

Loose stitches usually mean you are wrapping yarn too loosely around the needle or pulling too gently when you draw the new loop through. Try wrapping the yarn more deliberately and pulling with a bit more tension. Uneven stitches often improve after a few rows as your hands find a rhythm.

What does it mean when a pattern says "knit the knits and purl the purls"?

This instruction tells you to work each stitch the same way it appears on the needle. If the stitch looks like a V (a knit bump), knit it. If it looks like a bump (a purl bump), purl it. This keeps ribbed and textured patterns aligned and prevents them from shifting.

Can I switch between knit and purl in the middle of a row?

Yes. Many patterns alternate knit and purl stitches within a single row to create ribbing or seed stitch. The yarn position changes each time you switch — bring it to the front for purl, move it to the back for knit. This takes practice but becomes automatic.
