Knit and Purl Are the Foundation of All Knitting

Knit and purl are the only two stitches you need to learn to make almost any knitted fabric. Every sweater, blanket, hat, and scarf is built from combinations of these two stitches. Once your hands learn the motion of each one, you can follow any pattern because the pattern is just telling you which stitch to make in which order.

The difference between them is straightforward: a knit stitch pulls the working yarn through a loop from front to back, and a purl stitch pulls it through from back to front. That one change in direction creates different textures on the front and back of your fabric. A knit stitch looks like a small V on the front of your work. A purl stitch looks like a bump or a dash. When you alternate knit and purl stitches in the same row, you create ribbing. When you knit every row, you create garter stitch, which looks bumpy on both sides.

Key Takeaways

  • A knit stitch pulls yarn through a loop from front to back and creates a V shape on the front of your fabric.
  • A purl stitch pulls yarn through from back to front and creates a bump or dash on the front of your fabric.
  • Both stitches use the same basic motion—you just change where the yarn sits before you insert the needle.
  • Practicing these two stitches on a practice swatch for 10 to 15 minutes a day builds muscle memory faster than longer, less frequent sessions.
  • Tension—how tightly you hold the yarn—matters more than speed; loose, even stitches are easier to fix than tight, uneven ones.

How to Make a Knit Stitch

Hold your needles with the working yarn (the yarn attached to the ball) in your right hand, draped over your index finger. The needle with live stitches sits in your left hand. Insert the right needle through the first stitch on the left needle from left to right, going in through the front of the loop. The right needle should pass underneath the left needle.

Wrap the working yarn around the right needle, going from left to right. The yarn should pass over the top of the right needle and come down between the two needles. In one smooth motion, pull the right needle back through the loop on the left needle, bringing the new loop with it. Slip the old loop off the left needle. You have made one knit stitch. Repeat this motion for every stitch on the left needle until all stitches have moved to the right needle. Then swap the needles and begin the next row.

The most common mistake is inserting the needle in the wrong direction. If you go in from right to left, you will twist the stitch. If the yarn is in the wrong place when you wrap, the stitch will be loose or uneven. Practice the insertion and wrap separately before you try to do them smoothly together.

How to Make a Purl Stitch

Hold the needles the same way as for knit, but this time bring the working yarn to the front of your work before you insert the needle. The yarn should be resting between the two needles, closer to you. Insert the right needle through the first stitch on the left needle from right to left—the opposite direction from a knit stitch. The right needle should pass in front of the left needle, not underneath it.

Wrap the working yarn around the right needle from right to left. The yarn should go over the top of the right needle and come down on the far side. Pull the right needle back through the loop, bringing the new loop with it. Slip the old loop off the left needle. You have made one purl stitch. The motion is almost identical to a knit stitch, except the yarn starts in front instead of in back, and the needle goes in from the opposite direction.

Purl stitches are often slower at first because the yarn position feels awkward. Your hand will remember this position after a few rows. If your purl stitches are much looser than your knit stitches, you are probably wrapping the yarn too loosely. Wrap it the same way you do for knit, just with the yarn in front instead of back.

Tension: Why It Matters More Than Speed

Tension is how tightly you hold the yarn as it flows through your fingers. Even tension means each stitch is roughly the same size, which makes your fabric look neat and makes it easier to pick up dropped stitches or fix mistakes. Uneven tension makes some stitches loose and some tight, which creates a bumpy, unprofessional look even if the stitches themselves are correct.

The yarn should flow through your fingers with gentle, steady pressure—not so tight that you feel resistance, and not so loose that the yarn hangs slack. Most knitters hold the yarn over the index finger of the right hand and under the middle finger, which gives them control without forcing tension. Experiment with different finger positions until you find one that feels natural.

If you notice your stitches getting tighter as you work, you are probably tensioning the yarn too much as you wrap it. Loosen your grip slightly. If stitches are falling off the needle or look very loose, you may be wrapping too loosely or not pulling the working yarn tight enough after you complete each stitch. Practice on a small swatch for 10 to 15 minutes at a time rather than long sessions; short, focused practice builds muscle memory faster and prevents hand fatigue from making your tension worse.

Practice Stitches: Building a Swatch

Cast on 20 stitches using your preferred cast-on method. Knit every row for 10 rows. This creates garter stitch, which looks bumpy on both sides and is forgiving for beginners because mistakes are less obvious. Count your stitches at the end of each row to make sure you have not accidentally added or dropped any.

After 10 rows of garter stitch, switch to ribbing: knit one stitch, purl one stitch, repeat across the row. Do this for 10 rows. Ribbing is tighter than garter stitch and shows tension problems clearly, so it is excellent practice. You will notice that switching between knit and purl stitches in the same row requires moving the yarn from back to front or front to back between stitches. Move it smoothly without wrapping it around the needle.

Finish by knitting 10 more rows of garter stitch. Bind off all stitches. You now have a swatch that shows your progress. Keep it—in a month, you will see how much your tension has improved. If you notice dropped stitches or holes in your swatch, that is normal and part of learning. The swatch is practice, not a finished project.

Common Mistakes and How to Fix Them

The most common mistake is accidentally creating a yarn over (an extra loop) when you move the yarn between stitches. If the yarn is in front when you knit, or in back when you purl, you will wrap it around the needle without meaning to, creating a new stitch. Count your stitches at the end of each row. If you have more stitches than you started with, you made yarn overs. If you have fewer, you dropped stitches.

Twisted stitches happen when you insert the needle in the wrong direction or when you slip a stitch onto the right needle backwards. A twisted stitch looks like it is leaning to one side. If you notice this, you can usually fix it on the next row by inserting the needle in the opposite direction for that stitch only, which untwists it.

Dropped stitches are stitches that have fallen off the needle. If you notice when ready, pick up the needle and insert it through the loop from front to back. If the stitch has dropped several rows, use a crochet hook to pull the working yarn through each dropped loop, working from bottom to top. This is easier than ripping back and reknitting.

Holding the Needles: English and Continental Methods

There are two main ways to hold needles and yarn: English style and Continental style. Neither is better—they are just different, and each person finds one more comfortable.

In English style, you hold the working yarn in your right hand, over your index finger. You throw the yarn around the needle with your right hand for each stitch. This method is common in English-speaking countries and feels natural if you have experience with crochet.

In Continental style, you hold the working yarn in your left hand, usually over your index finger. You use the needle to pick up the yarn rather than throwing it. This method is faster once you develop muscle memory because your hand moves less.

Start with whichever method feels more natural to you. You can switch later if you want, but learning one method well is more important than trying to learn both at once. Your hands will develop the muscle memory for whichever method you practice consistently.

Frequently Asked Questions

Why do my knit stitches look different from my purl stitches?

Knit and purl stitches are supposed to look different. A knit stitch shows a V on the front, and a purl stitch shows a bump. If your knit stitches look bumpy or your purl stitches look like Vs, you may have twisted them or inserted the needle in the wrong direction. Check that you are inserting the needle from left to right for knit and right to left for purl.

How long does it take to get comfortable with these stitches?

Most people feel comfortable with basic knit and purl stitches after 3 to 5 hours of practice spread over a week or two. Your hands will remember the motion faster if you practice in short sessions—15 minutes a day is better than one 2-hour session. After a month of regular practice, the motions become automatic and you can focus on following a pattern instead of thinking about each stitch.

What should I do if I keep dropping stitches?

Dropped stitches usually mean the working yarn is too loose or you are not pulling it tight enough after completing each stitch. After you pull the new loop through, gently tighten the working yarn so the stitch sits snugly on the needle. If stitches are still falling off, your needles may be too large for your yarn. Check that the needle size matches what the yarn label recommends.

Can I knit and purl with different yarn weights?

Yes. The stitch itself does not change, but thicker yarn creates larger stitches and thinner yarn creates smaller ones. You will need larger needles for thick yarn and smaller needles for thin yarn. The yarn label always recommends a needle size—start there and adjust if your fabric feels too loose or too tight.

Is it normal for my hands to hurt when I first start knitting?

Mild hand fatigue is normal when you are learning because you are using muscles in a new way. Stop and rest if your hands hurt. Pain is different from fatigue—if you feel sharp pain, stop when ready and rest for a day or two. You may be tensioning the yarn too tightly or gripping the needles too hard. Relax your grip and let the needles rest in your hands rather than clenching them.
