What a Purl Stitch Is and Why You Need It

A purl stitch is the reverse of a knit stitch. Where a knit stitch pulls yarn from the back of your work toward the front, a purl stitch pulls yarn from the front toward the back. The result looks like a bump or ridge on the side facing you. Learning to purl doubles what you can make—you can now create textured patterns, reverse stockinette fabric, and ribbing, which is essential for cuffs and edges that stretch and recover.

Most knitting patterns mix knit and purl stitches. Ribbing (alternating knit and purl columns) appears on nearly every sweater, hat, and sock. Garter stitch (knitting every row) looks the same on both sides, but once you know how to purl, you can make stockinette stitch (knit one row, purl one row), which is smoother and shows stitch definition better. Without the purl stitch, you are limited to garter stitch and a few other basic textures.

Key Takeaways

  • A purl stitch is worked with yarn held in front of your needles, and you insert the needle from right to left through the loop on your left needle.
  • The working yarn stays in front of your work for the entire purl stitch, unlike a knit stitch where it stays in back.
  • Your hands and fingers move the same way as in a knit stitch—the difference is only where the yarn sits and which direction the needle enters the loop.
  • Purling feels awkward at first because the yarn position is reversed, but the motion becomes automatic after 10 to 15 minutes of practice.
  • Tension often loosens when you switch from knit to purl because your hand position changes; watch your tension and adjust your grip if stitches suddenly look bigger.

How to Hold Your Needles and Yarn for a Purl Stitch

Before you insert the needle, position your yarn in front of your work. If you knit with yarn in your right hand (English style), bring the yarn forward between your needles so it rests on top of your index finger. If you knit with yarn in your left hand (Continental style), the yarn is already in front—no adjustment needed. The key difference from a knit stitch is that the yarn must be forward, not back.

Hold your left needle (the one with active stitches) in your left hand the same way you do for knit stitches. Your right needle should be empty and ready to work. If you are new to knitting, use needles one or two sizes larger than your yarn calls for—this gives you more room to see what you are doing and makes it easier to insert your needle through the loop.

The Step-by-Step Purl Stitch Motion

Insert your right needle through the loop on your left needle from right to left (the opposite direction from a knit stitch). Push the needle tip through the loop so it comes out on the side closest to you. The needle should pass in front of the loop, not behind it. This is the biggest difference from knitting: your needle enters from the front side of your work.

Once the needle is through, wrap the working yarn around the right needle tip counterclockwise (the same wrap direction as a knit stitch). Pull the right needle back through the loop, drawing the new loop with it. The old loop slides off your left needle, and you have completed one purl stitch. The new loop stays on your right needle.

Repeat this motion for every stitch across the row. Your right needle will gradually fill with stitches while your left needle empties. When you reach the end of the row, switch the needles so the full needle is now in your left hand, and purl the next row the same way.

Common Mistakes and How to Avoid Them

The most frequent error is inserting the needle from left to right instead of right to left. This twists the stitch and makes it harder to work on the next row. Before you wrap the yarn, look at your needle angle: it should be pointing away from you and slightly downward, entering the loop from the front. If the needle is pointing toward you, you have the direction backward.

A second common problem is letting the yarn slip to the back of your work while you are purling. This accidentally creates a yarn over (an extra loop) and adds a stitch you did not intend. Keep the yarn visibly in front of your needles the entire time you are purling. If you need to knit the next row, move the yarn to the back before you start.

Tension often becomes loose when you switch between knit and purl rows because your hand position changes. Your fingers are now holding the yarn in a different spot, and you may unconsciously relax your grip. After you complete a purl stitch, gently tighten the loop on your right needle by pulling the working yarn slightly. This takes practice, but your tension will even out after a few rows.

Practice Exercises to Build Speed and Consistency

Cast on 20 stitches using a straightforward cast-on method. Knit one row to warm up. On the second row, purl every stitch across. Repeat: knit one row, purl one row, for at least 10 rows. This creates stockinette stitch and forces you to switch between knit and purl, which is where most tension problems show up. Stop and look at your work every two rows. The stitches should be roughly the same size on both the knit and purl rows.

Once stockinette feels steady, try ribbing. Cast on 20 stitches and work in a pattern of knit 2, purl 2 for 10 rows. This means you knit two stitches, then purl two stitches, then repeat across the row. Ribbing is harder because you switch yarn position every two stitches, but it is also the most useful pattern in real projects. Spend 15 to 20 minutes on ribbing practice, and your purl stitch will feel much more automatic.

When Your Purl Stitches Look Uneven

Uneven purl stitches usually mean one of three things: your tension is too tight, your tension is too loose, or you are inserting the needle at a slightly different angle each time. Tight stitches look small and hard to work into on the next row. Loose stitches look large and floppy. Aim for stitches that are the same size as your knit stitches on the row below.

If your first purl stitch of each row is always loose, you are probably pulling the yarn too hard after you complete the last knit stitch. Instead, pull gently and let the stitch settle on the needle before you start the next row. If your purl stitches are consistently tighter than your knit stitches, relax your grip slightly when you hold the yarn in front. You may be squeezing it harder than you do when it is in back.

Uneven needle insertion (going in at different angles) creates stitches that sit at different heights. Watch your needle angle as you work. It should enter the loop at roughly the same spot every time—usually through the center of the loop, not the edge. After 20 to 30 rows of practice, this becomes automatic and you will stop thinking about it.

Moving Forward: Purl Stitches in Real Patterns

Once you can purl a full row without dropping stitches or accidentally adding extras, you are ready for straightforward patterns. Look for patterns labeled "beginner" that use only knit and purl stitches. Garter stitch scarves (knit every row) are your first project, but a stockinette scarf (knit one row, purl one row) is the next logical step. Stockinette shows off your tension and teaches you to switch between knit and purl smoothly.

After a stockinette scarf, try a project with ribbing, such as a straightforward hat or a pair of socks. Ribbing is where the purl stitch becomes truly useful—it creates the stretchy edge that keeps hats and socks from sliding off. At this point, purling will feel as natural as knitting, and you will be ready to explore more complex stitch patterns.

Frequently Asked Questions

Why does my purl stitch look different from my knit stitch?

A purl stitch creates a bump or ridge that faces you, while a knit stitch creates a V-shape. This is not a mistake—it is the intended look. When you alternate knit and purl rows, the bumps and V-shapes stack on top of each other and create the smooth stockinette fabric. If your purl stitches look twisted or distorted compared to your knit stitches, check that you are inserting the needle from right to left and that your yarn stays in front the entire time.

Can I purl if I knit Continental style?

Yes. Continental purling is actually faster than English purling because your yarn hand does not move as far. Keep the yarn in front of your work (it already is), insert the needle from right to left, and use your left index finger to push the yarn onto the needle tip. The motion is smaller and quicker than English purling, and many knitters find it easier once they learn it.

What if I accidentally purl when I should have knitted?

If you notice the mistake in the same row, drop the stitch and redo it as a knit stitch. If you do not notice until the next row, you can usually leave it—one wrong stitch in a scarf or blanket is invisible from a distance. In fitted garments like sweaters, a single wrong stitch can throw off the pattern, so it is worth fixing. Use a crochet hook to pick up the dropped stitch and work it back up to the current row.

How long does it take to get comfortable purling?

Most knitters feel comfortable purling after 30 to 60 minutes of focused practice. The motion becomes automatic after a few projects. If purling still feels awkward after an hour, take a break and come back to it the next day. Your hands need time to build the muscle memory, and rest actually speeds up learning.

Should I use the same needles for purling as I do for knitting?

Yes, use the same needles. The only time to switch needle size is if your pattern calls for it (for example, smaller needles for ribbing to make it tighter). Needle material does not matter for learning to purl—bamboo, metal, and plastic all work the same way. Use whatever needles feel comfortable in your hands.
