The knit stitch looks like a V, and the purl stitch looks like a bump

The knit stitch creates a V-shaped loop on the front of your fabric. When you look at the right side of your knitting, each knit stitch appears as a small, pointed V standing upright. The purl stitch creates the opposite texture: a horizontal bump or ridge. If you flip a knit stitch to the back, you see a purl bump. If you flip a purl stitch to the back, you see a V.

This difference matters because it changes how your fabric looks and feels. Stockinette stitch—the smooth, flat fabric you see on most sweaters—is made by knitting one row and purling the next row. Garter stitch—the bumpy, textured fabric—is made by knitting every row. Understanding what each stitch looks like helps you follow patterns, fix mistakes, and choose the right stitch for what you are making.

Key Takeaways

  • A knit stitch shows as a V on the front of your fabric, with a bump on the back.
  • A purl stitch shows as a bump on the front of your fabric, with a V on the back.
  • Combining knit and purl stitches in different patterns creates different textures: smooth, bumpy, or decorative.
  • Learning to recognize these stitches by sight helps you read your knitting and catch mistakes before they spread.

What a knit stitch looks like up close

Hold your knitting up to the light and look at a single knit stitch from the front. You will see a clear V shape with a vertical line running down the center. The two legs of the V point downward, and the point sits at the top. This V is made of yarn that loops around itself in a specific way: the working yarn comes from behind the needle, goes through the loop on the left needle, and comes back out to the front.

On the back of a knit stitch, you see a horizontal bump or ridge. This bump is the same loop viewed from the opposite side. When you are working stockinette stitch, you knit on the right side (the side facing you) and purl on the wrong side (the back). This creates rows of Vs on the front and rows of bumps on the back. The front looks smooth and flat because the Vs nest together neatly.

What a purl stitch looks like up close

A purl stitch is the reverse of a knit stitch. On the front of your fabric, a purl stitch appears as a horizontal bump or ridge, just like the back of a knit stitch. The bump sits on top of the stitch below it. When you purl, the working yarn comes from the front of the needle, goes through the loop on the left needle, and comes back out to the back.

On the back of a purl stitch, you see a V shape. This is why garter stitch—knitting every row—looks the same on both sides: you are alternating between seeing the front of a knit stitch (a V) and the front of a purl stitch (a bump) as you work. The bumps and Vs stack on top of each other, creating that characteristic ridged texture.

How knit and purl combine to make different patterns

The real power of knit and purl comes from combining them. Stockinette stitch uses knit stitches on one side and purl stitches on the other to create a smooth, flat fabric. Garter stitch uses only knit stitches (or only purl stitches) to create a bumpy, reversible fabric. Ribbed stitch alternates between columns of knits and purls to create vertical stretchy lines.

Decorative patterns like seed stitch alternate single knit and purl stitches in a checkerboard pattern, creating a textured, bumpy fabric that looks the same on both sides. Cable patterns use knit stitches crossed over each other to create twisted, rope-like textures. Once you can recognize a knit and a purl by sight, you can read any pattern and understand what the finished fabric will look like before you cast on.

Common mistakes when identifying stitches

The most common mistake is confusing a purl stitch with a twisted or loose knit stitch. A purl stitch is always a horizontal bump, even if your tension is uneven. If you see something that looks like a V but feels loose or sits at an odd angle, it is probably a knit stitch with loose tension, not a purl. Loose stitches still have the V shape; they are just bigger.

Another mistake is looking at your stitches from the wrong side. If you flip your knitting over to check a stitch, remember that knits and purls swap places. A V on the back is a purl on the front. A bump on the back is a knit on the front. Always look at the side of the fabric that is facing you when you are working to identify what stitch you just made.

How to practice spotting stitches

The easiest way to learn is to knit a small swatch using a light-colored yarn and large needles. Cast on 10 stitches and knit 10 rows. Look at the front: you see rows of bumps (purls) and rows of Vs (knits) alternating. Now flip it over and look at the back: the pattern reverses. This is stockinette stitch, and it shows you exactly how knits and purls relate to each other.

Next, cast on 10 stitches and knit every row for 10 rows. Look at the front: you see bumps and Vs stacked together in a dense, textured pattern. Flip it over: it looks exactly the same. This is garter stitch. Once you have made both swatches, you can see the difference between a smooth fabric and a bumpy one, and you will recognize these stitches when ready in any project.

Why recognizing stitches matters when you knit

Reading your stitches is how you catch mistakes before they ruin rows of work. If you are supposed to be knitting stockinette stitch and you see a bump where a V should be, you know you accidentally purled when you should have knitted. Catching this one stitch is much easier than ripping out five rows because you did not notice the mistake until later.

Recognizing stitches also helps you follow patterns without getting lost. Many patterns use abbreviations like K (knit) and P (purl), and if you can see what each stitch looks like, you can check your work against the pattern as you go. You can also modify patterns or create your own by understanding how different stitch combinations create different textures and effects.

Frequently Asked Questions

What if my knit stitches look bumpy instead of smooth?

Bumpy knit stitches usually mean your tension is too loose. The V shape is still there, but the stitch is stretched out and sits lower than it should. Practice tightening your working yarn slightly as you knit. Your stitches will still be recognizable as Vs, just neater and more even.

Can I tell the difference between knit and purl stitches if I am colorblind?

Yes. The difference is in the shape and texture, not the color. A knit stitch is a V shape with a vertical line down the center. A purl stitch is a horizontal bump or ridge. You can feel the difference by running your finger across the fabric: knits feel smooth, purls feel bumpy. Texture is more reliable than color anyway.

Why do my purl stitches look different from my knit stitches if they are the same yarn?

They look different because they are made in opposite directions. A knit stitch pulls the yarn from back to front; a purl stitch pulls it from front to back. This creates the V and bump shapes. The yarn itself is the same, but the way it loops around the needle changes how it sits on the fabric.

Do I need to memorize what knit and purl look like, or will I learn it naturally?

You will learn it naturally through practice, but looking at your stitches intentionally speeds up the process. Spend a few minutes after each knitting session looking at your work and identifying stitches. Within a few projects, you will recognize them when ready without thinking about it.

What if I cannot see my stitches clearly because the yarn is dark?

Use a light-colored yarn for practice swatches, or hold your knitting up to bright light. You can also take a photo with your phone's camera and zoom in; sometimes the camera picks up details your eye misses. Once you understand the shapes, you will be able to identify stitches in any yarn color.
