A granny square is the friendliest shape in crochet. It forgives uneven tension, it grows quickly, and one square teaches you enough to make blankets, cushions, bags and cardigans. If you can make a chain and a treble crochet, you can make this — every round uses the same small cluster of stitches, so the pattern soon becomes something your hands remember rather than something you have to keep reading.

The instructions below use UK terms. Work the first two rounds slowly and the rest will follow easily.

What makes the granny square so good for beginners is that it is built on repetition. Once you have the first round sorted, every round after it is essentially the same sequence — a cluster of three trebles into a gap, a chain to bridge the corner — just worked more times. You are not learning ten new things; you are learning one thing and doing it with increasing confidence. That is why so many people who "can't crochet" find themselves finishing a whole blanket after starting with a single square.

What You Need Before You Start

Keep your first square simple: a smooth double knitting yarn and a 4mm hook are ideal, though any yarn works if you match the hook to the ball band.

• Yarn: smooth DK in two or three colours. Cotton and acrylic are easy to read; fluffy or textured yarns hide your stitches and make learning harder.
• Hook: 4mm for DK, or whatever the ball band suggests. If your square curls at the corners your tension is tight — try half a millimetre larger.
• Extras: scissors, a blunt tapestry needle for weaving in ends, and a stitch marker if you struggle to spot the first stitch of a round.

Two colours are plenty for a first attempt, and even one colour will teach you everything you need to know. If you are buying yarn specially, pick a light shade in a plain, plump yarn rather than a dark or splitty one — you will see your stitches far more clearly, and mistakes are much easier to spot before they become a whole round you have to unpick.

The Stitches You'll Be Using

Three stitches and a chain, and that is the whole square.

• Chain (ch) — yarn over, pull through the loop on the hook.
• Slip stitch (sl st) — insert the hook, yarn over, pull through everything on the hook.
• Treble crochet (tr) — yarn over, insert the hook, pull up a loop, yarn over and pull through two loops, yarn over and pull through the last two.

If you learned from American patterns, note the translation: a UK treble is a US double crochet. Granny squares are almost always built from trebles, so a US pattern that calls for "dc clusters" means trebles here.

Every granny square you have ever admired is just the same little three-treble cluster, repeated in a ring until it turns into a square. Nothing else is going on.

Round One: The Centre Ring

Everything starts from a small ring.

1. Make a slip knot and chain 4. Join with a slip stitch into the first chain to form a ring. Do not twist it — the chain should lie flat as a neat little loop.
2. Chain 3. This counts as your first treble and gives the round its height.
3. Work 2 trebles into the centre of the ring. You now have a cluster of 3 trebles, counting the chain-3.
4. Chain 3, then work 3 trebles into the ring. Repeat this twice more, so you end up with four clusters separated by four chain-3 corners.
5. Chain 3 one last time and join with a slip stitch to the top of the beginning chain-3. Fasten off if you are changing colour.

Tug the starting tail gently to close the centre hole, then weave it in later. Do not worry if your first ring looks a little lumpy — block it at the end and it will settle.

Round Two: Growing the Square

This is where the square shape appears. Join your new colour in any corner chain-3 space, or continue with the same colour if you prefer.

1. Join the yarn in a corner space and chain 3, then work 2 trebles into the same corner.
2. Chain 1, then work 3 trebles into the next corner space. Chain 3, then 3 more trebles into the same space — that is your new corner.
3. Repeat step 2 around, finishing with a join into the top of the first chain-3.

Notice the pattern: 3 trebles into each corner, chain 3 between the two clusters that make the corner, chain 1 between corners. That single rule carries you through every remaining round.

Round Three and Beyond

Each new round starts the same way and adds one more cluster along each side.

1. Join in a corner, chain 3, and work 2 trebles into that corner.
2. Chain 3, work 3 trebles back into the same corner to complete it.
3. Chain 1. Work 3 trebles into the next chain-1 space along the side.
4. Chain 1 and repeat across the side until you reach the next corner, then repeat the corner from step 2.
5. Continue around and join with a slip stitch.

Three rounds gives you a coaster. Six rounds makes a decent cushion panel. Continue until the square measures the size you want — a common blanket square is around 15cm, which is usually six or seven rounds in DK.

Changing Colour Cleanly

Fasten off at the end of a round, leaving a 10cm tail. Join the new colour with a slip stitch into a corner space, then chain 3 and carry on. Weave the tails in horizontally through the backs of the stitches, changing direction once, so they never work loose. If you want a striped square without endless ends, carry the unused colour up the side and crochet over it as you go.

Fixing Common Problems

• Square curls like a bowl: your tension is too tight. Go up a hook size or loosen your chain-1 spaces.
• Corners look rounded, not square: you may be skipping the chain-3 inside the corner. Both clusters need to sit in the same corner space.
• Round has grown a mystery extra cluster: you have worked into a chain-1 space twice. Count clusters as you go — each side gains exactly one per round.
• Holes look too big: normally fine. Granny squares are meant to be airy. Blocking closes them up considerably.
• Square is wonky: almost certainly the first round pulling tight. Redo it slightly looser and the whole square will sit flatter.

Turning Your Squares Into Something Useful

Once you have a pile of squares, join them by holding two right sides together and slip stitching through the back loops only, or by crocheting them together with a simple double crochet seam for a raised, decorative line. A blanket is the obvious project: roughly 48 squares of 15cm will give you a generously sized throw. Smaller squares become coasters, pot holders, or a cushion cover. Sewn onto a tote bag or a plain jumper, a handful of squares lifts something ordinary into something handmade.

Read your finished square before you decide it is wrong. Lay it flat on a table, measure it across the middle, and check that the sides are straight and the corners are defined. A square that measures 15cm on one side and 14.5cm on the other is not a failure — it is a square that needs blocking, or the next one needs a slightly looser hand. Consistency between squares matters far more than perfection in any single one.

Make five squares. By the fifth, you will not need this tutorial at all — and that is the real point of the granny square. It teaches your hands a rhythm that carries into everything else you crochet.
