The basic knit stitch creates a recognizable V-shaped pattern

A knit stitch looks like a small V or loop sitting upright on your fabric. When you look at knitted material straight on, you see columns of these Vs stacked on top of each other. Each V is one stitch, and the way they interlock creates the fabric's structure. The right side of a knit — the side you wear facing out — shows these Vs clearly. The back side, called the purl side, looks bumpy and textured because you are seeing the loops from behind.

The size and clarity of these Vs depends on your yarn weight and needle size. Thick yarn on large needles makes the Vs bold and straightforward to see. Thin yarn on small needles creates tiny, tight Vs that almost blur together. Either way, the V shape is the signature of a knit stitch, and once you know what to look for, you will spot it on any knitted sweater, blanket, or scarf.

Key Takeaways

  • A knit stitch appears as an upright V-shape when viewed from the front of the fabric, with columns of these Vs running vertically down the piece.
  • The back of a knit stitch shows bumps and texture because you are looking at the loops from the reverse side, which is called the purl side.
  • Garter stitch, made by knitting every row, creates horizontal ridges that look like bumpy lines running across the fabric.
  • Stockinette stitch, the most common pattern, alternates knit and purl rows to create smooth Vs on the front and bumps on the back.
  • Ribbed knits have vertical columns of bumps and Vs running side by side, which stretch and hug the body.

Garter stitch looks like horizontal ridges

Garter stitch is the simplest knit pattern to recognize. It looks like a series of horizontal bumpy lines running across your fabric. You create garter stitch by knitting every single row, never purling. Because you knit both sides, the fabric looks the same on the front and back — bumpy all over.

Garter stitch is thick, spongy, and does not curl at the edges the way stockinette does. It lies flat naturally. If you run your finger across garter stitch, you feel distinct ridges. If you look at it from the side, you see the fabric has real depth and texture. Garter stitch is common in blankets, scarves, and dishcloths because it is durable and forgiving of beginner mistakes.

Stockinette stitch has smooth Vs on the front and bumps on the back

Stockinette stitch is the most common knit pattern you will see on store-bought sweaters and fitted garments. It is made by alternating a knit row with a purl row. The front side shows those clean, upright Vs in neat columns — this is the side meant to be seen. The back side is all bumps, which is why stockinette looks completely different depending on which side you are looking at.

Stockinette has a smooth, polished appearance on the front. The fabric drapes well and shows stitch detail clearly. The downside is that stockinette curls at the edges if you do not bind off or add a border. The back side, called reverse stockinette, is sometimes used intentionally as a design feature — you will see it on some sweaters where the bumpy texture is the point.

Ribbed knits have vertical columns of bumps and Vs

Ribbed knit looks like vertical stripes of bumps and Vs running side by side. You create ribbing by alternating knit stitches with purl stitches on the same row, then repeating that pattern on every row. Common ribbing patterns are 1x1 (one knit, one purl) or 2x2 (two knits, two purls).

Ribbed fabric is stretchy and hugs the body, which is why you see it on cuffs, necklines, and the waistbands of sweaters. The bumpy columns pull in and the smooth columns push out, creating that distinctive accordion-like texture. Ribbing is tighter and more elastic than stockinette, so it holds its shape better around wrists and necks.

Cable knit has twisted, rope-like patterns

Cable knit looks like thick twisted ropes running vertically through the fabric. The ropes are created by crossing groups of stitches over each other in a specific order. A straightforward cable might cross four stitches over four stitches. More complex cables can have multiple twists and create intricate braided or woven effects.

Cable knit is raised and three-dimensional. When you run your hand over it, you feel the texture clearly. Cable patterns are common on sweaters, hats, and blankets because they look impressive and are warm. The downside is that cables use more yarn than simpler stitches, so a cable sweater is heavier and takes longer to knit.

Seed stitch looks like scattered bumps

Seed stitch is made by alternating knit and purl stitches in a checkerboard pattern — knit, purl, knit, purl on one row, then purl, knit, purl, knit on the next row. The result looks like tiny scattered bumps all over the fabric, almost like sesame seeds, which is where it gets its name.

Seed stitch is reversible, meaning both sides look the same. It does not curl and lies flat naturally. The texture is subtle but visible, and the fabric has a slightly bumpy, nubby feel. Seed stitch is common on blankets, scarves, and garments where you want texture without the boldness of garter stitch or the smoothness of stockinette.

Lace knit has holes and open patterns

Lace knit includes deliberate holes and open spaces created by yarn overs and decreases. A yarn over is when you wrap yarn around the needle without knitting a stitch, which creates a hole. A decrease is when you combine two stitches into one, which shifts the fabric and creates the lace pattern.

Lace can range from subtle scattered holes to bold, intricate patterns that look almost like filigree. Lace knit is lighter and more delicate than solid stitches, so it is common on shawls, summer garments, and decorative pieces. The holes let light and air through, making lace knit breathable and elegant.

Frequently Asked Questions

How can I tell the difference between knit and purl at a glance?

A knit stitch looks like an upright V. A purl stitch looks like a bump or a small horizontal line. If you see columns of Vs, you are looking at the knit side. If you see bumps, you are looking at the purl side or a pattern that uses purls on the front.

Why does my knit curl at the edges?

Stockinette stitch naturally curls because the knit side wants to roll inward and the purl side wants to roll outward. Garter stitch and ribbing do not curl because they use both knits and purls evenly. To stop curling, add a border of garter stitch or ribbing around the edges, or use a pattern that does not curl.

What does a dropped stitch look like?

A dropped stitch appears as a vertical line or ladder running down your fabric where a stitch has come undone and unraveled. You will see a gap or a loose loop. Dropped stitches are common in stockinette and straightforward to spot because the Vs are missing in that column. You can pick them back up with a crochet hook.

Can you tell how experienced a knitter is by looking at their work?

Yes. Beginner knit often has uneven tension — some stitches are tight and some are loose, so the Vs are different sizes. Edges may be messy or curled. Advanced knit has consistent stitch size, clean edges, and even tension throughout. The difference is most visible in stockinette, where loose tension makes the Vs look sloppy.

What does it mean when a knit looks "blocked"?

Blocking is when a knitter washes and shapes the finished piece, then lets it dry flat. A blocked knit looks smooth, even, and professional. The stitches are uniform, the edges are straight, and the fabric lies flat. Unblocked knit can look rumpled or wavy. Blocking is especially important for lace and stockinette.
