The Two Stitches That Build Every Knit Project

Every knitted fabric is made from two stitches: the knit stitch and the purl stitch. The knit stitch creates a smooth V-shaped bump on the front of your work. The purl stitch creates a horizontal bump and sits on top of the knit stitch. Once you can make both, you can combine them to create texture, patterns, and finished pieces.

You do not need to memorize complicated hand positions. The motion is the same every time: insert your needle, wrap yarn around it, and pull through. The only difference between knit and purl is which direction your needle enters the stitch and which side of the needle you wrap the yarn around.

Key Takeaways

  • The knit stitch is made by inserting your right needle through a loop from left to right, wrapping yarn around the needle, and pulling a new loop through.
  • The purl stitch uses the same motion but in reverse: your needle enters from right to left, and you wrap yarn on the opposite side of the needle.
  • Both stitches start with loops already on your left needle, usually cast on before you begin knitting.
  • Tension—how tightly you pull the yarn—matters more than speed; loose, even stitches are easier to work with than tight, uneven ones.
  • Practicing one stitch at a time on a small swatch of yarn helps you build muscle memory before moving to a full project.

How to Make a Knit Stitch Step by Step

Hold your needles so the left needle has loops on it and the right needle is empty. The working yarn (the yarn attached to the ball) hangs from the right side of your work. Insert the tip of your right needle through the first loop on the left needle, going from left to right, so the needles form an X shape.

Wrap the working yarn around the shaft of the right needle, going under and then over the needle tip. This wrap is called a yarn over. Pull the right needle backward and down, drawing the new loop through the old loop on the left needle. Slide the old loop off the left needle. You now have one new stitch on the right needle.

Repeat this motion with each loop on the left needle until all loops have moved to the right needle. At the end of the row, swap the needles so the full needle is now in your left hand, and the empty needle is in your right hand. Begin the next row the same way.

How to Make a Purl Stitch Step by Step

The purl stitch looks different on the fabric but uses the same basic motion. Hold your needles the same way, with loops on the left needle and the working yarn on the right side. This time, insert your right needle through the first loop from right to left—the opposite direction from a knit stitch. The needles still form an X, but your right needle enters from the front.

Wrap the working yarn around the right needle, going over the top and then under the needle shaft. Pull the right needle backward, drawing the new loop through. Slide the old loop off the left needle. You have completed one purl stitch.

Repeat across the row. When you turn to work the next row, the purl stitches you just made will look like horizontal bumps facing you. If you purl every row, these bumps stack and create a textured fabric called garter stitch. If you alternate knit rows and purl rows, you create stockinette stitch, which looks smooth on one side and bumpy on the other.

Why Tension Matters More Than Speed

Tension is how tightly you hold and pull the yarn as you work. Loose tension makes stitches that are straightforward to see and straightforward to fix if you make a mistake. Tight tension makes stitches that are hard to insert your needle into and can make your hands tired. Neither is wrong, but consistency matters far more than which you choose.

If your stitches are very loose on some rows and very tight on others, your finished piece will look uneven and wavy. Spend your first few practice rows focusing on keeping the same tension throughout, even if your stitches are larger than you want them to be. You can always adjust your tension once you have built the muscle memory for the stitch itself.

Many new knitters pull the yarn too hard after each stitch, thinking tighter stitches are better. This actually makes the next stitch harder to work into and slows you down. A light, steady pull is faster and produces a more even fabric.

Common Mistakes and How to Spot Them

The most common mistake is accidentally creating an extra loop instead of replacing the old stitch with a new one. This happens when you wrap the yarn but forget to slide the old loop off the left needle. You will see your stitch count growing row by row, and your fabric will get wider instead of staying the same width. If this happens, count your stitches at the end of each row until you find where the extra loop appeared, then drop it off the needle.

Another frequent error is twisting your stitches, which happens when you insert your needle through the loop in the wrong direction or wrap the yarn the wrong way. Twisted stitches look like they are leaning to one side instead of sitting straight. They are not a problem in themselves, but they make the next row harder to work into. If you notice twisted stitches, you can usually just keep going—they become less noticeable as you gain experience.

Dropped stitches occur when a loop slides off your needle without being secured. You will see a hole in your fabric with a strand of yarn running down from it. This is fixable: use a crochet hook or a smaller needle to pick the loop back up and pull it tight, working from the dropped stitch upward to the current row.

Practicing on a Swatch Before a Full Project

A swatch is a small rectangle of knitting, usually 4 to 6 inches square, made just to practice. Cast on 15 to 20 stitches using whatever yarn and needles you plan to use for your project. Knit 20 to 30 rows, then bind off. This takes 20 to 30 minutes and teaches you how your hands work with that specific yarn and needle size.

Swatches show you whether your tension is even, whether you can maintain a consistent stitch size, and whether the yarn and needles feel comfortable in your hands. They also let you practice fixing mistakes on a small piece before you invest time in a full project. Many knitters keep their swatches and use them to remember how a particular yarn behaved, which is useful if you want to knit the same pattern again months or years later.

Frequently Asked Questions

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

The direction your needle enters the stitch and the side of the needle you wrap the yarn around are reversed. This creates stitches that look different on the fabric. A knit stitch shows a V on the front; a purl stitch shows a horizontal bump. Combining them in different patterns creates all the textures in knitting.

Do I have to cast on stitches before I can make my first stitch?

Yes. Casting on creates the first row of loops on your needle. Without cast-on stitches, you have nothing to insert your needle into. There are many cast-on methods, but they all produce a row of loops ready for your first knit or purl stitch.

How do I know if I am holding the needles correctly?

There is no single correct way. Some knitters hold needles like pencils, some like chopsticks, and some tuck one needle under their arm. The right way is whatever lets you insert your needle smoothly, wrap yarn consistently, and work for 20 minutes without hand pain. Experiment with different positions during your swatch practice.

What happens if I accidentally make a purl stitch when I meant to make a knit stitch?

You will see a bump instead of a V in that spot. If you notice it right away, you can drop back one row, fix the stitch, and knit forward again. If you do not notice until later, you can usually just keep going—one misplaced stitch is rarely noticeable in a finished piece, especially if the pattern uses both knit and purl stitches.

Can I use any yarn and needles to practice?

Yes, but medium-weight yarn in a light color on size 8 to 10 needles is easiest to learn on. Thin yarn and small needles make it hard to see your stitches and insert your needle. Thick yarn can be stiff and tiring to work with. Light colors let you see the stitch structure clearly, which helps you spot mistakes and understand what you are doing.
