Granny Square Tutorial: Crochet the Classic Motif Step by Step

If crochet has a logo, it's the granny square: a little quilt block of clustered stitches that has been turning leftover yarn into blankets since the 1800s — and is currently all over fashion runways and handmade cardigans. It's also one of the best skill-builders in crochet: rounds, clusters, corners and color changes, all in one palm-sized project.

What You Need to Know First

This tutorial uses US terms. You should be comfortable with the chain (ch), slip stitch (sl st), and double crochet (dc). If you're not there yet, spend an evening with our beginner's guide first.

The granny square is built from one repeating unit: the granny cluster — 3 double crochets worked into the same space. Corners are simply two clusters separated by 2 chains. That's the entire secret.

Round 1: The Center

1. Chain 4, join to the first chain with a slip stitch to form a ring. (Prefer the magic ring? It works perfectly here and closes the center hole tighter.)
2. Chain 3 — this counts as your first double crochet.
3. Work 2 dc into the ring, then chain 2. That's your first cluster and corner space.
4. Repeat (3 dc into the ring, ch 2) three more times.
5. Join to the top of the starting chain-3 with a slip stitch.

You now have a tiny square: 4 clusters, 4 corner spaces.

Round 2: Turning Corners

1. Slip stitch over to the nearest corner space, then chain 3.
2. In that corner space work: 2 dc, ch 2, 3 dc — a corner (two clusters sharing the space).
3. Chain 1, then in the next corner space work another corner (3 dc, ch 2, 3 dc).
4. Repeat around; join with a slip stitch to the top of the chain-3.

Round 3 and Beyond: The Rhythm

From here every round follows the same logic:

• In each corner space: 3 dc, ch 2, 3 dc.
• In each side space (the ch-1 gaps between clusters): 3 dc, ch 1.

Each round adds one more cluster per side. Keep going as long as you like — a giant single granny square makes a perfectly respectable baby blanket on its own.

Changing Colors (the Fun Part)

Classic grannies change color every round. Finish a round, fasten off, then join the new color in any corner space with a standing chain-3 (or a slip knot + slip stitch, then ch 3). Joining in a different corner each round hides the "seam" of joins that otherwise stacks up one side of your square. Leave 15 cm tails and weave them in as you go — a granny blanket can generate a frightening number of ends.

Fixing the Two Classic Problems

The twist: granny squares famously start to spiral like a pinwheel after several rounds. Causes: tight tension and tight corner chains. Solutions: relax your ch-2 corners, go up a hook size, or turn your work after each round (working alternating rounds clockwise/counter-clockwise cancels the twist entirely).

The curl: if the square cups like a bowl, you're adding too much; if it ruffles, check you're not doubling up side clusters. When in doubt, recount: each side should grow by exactly one cluster per round.

A 10-minute steam blocking at the end — pin the square flat, hover a steam iron over it, let it cool — makes even wobbly squares look bakery-fresh.

What to Make With Them

• Blankets: the eternal classic. Join squares with slip stitch, whip stitch, or the pretty join-as-you-go method.
• Cardigans and vests: hugely fashionable right now; many patterns are literally rectangles of joined squares.
• Bags, cushion covers, coasters: one to eight squares and an afternoon.

Make one square a day with leftover yarn, and in three months you'll have a blanket that cost almost nothing and looks like heirloom material.
