A granny square is a small motif worked in the round, usually made from clusters of double crochet stitches separated by chain spaces. It is one of the most enduring patterns in crochet because it is portable, uses small amounts of yarn, and can be made in a single color or with a different color each round. Once you can make one square, you can make dozens and join them into blankets, pillows, bags, scarves, and sweaters.

This guide assumes you know how to make a slip knot, chain, and double crochet. If those are still new, practice them for a few rows before starting in the round.

Materials and Setup

For your first granny square, choose medium-weight yarn, labeled #4 or worsted, in a light, solid color. Light colors make it easier to see chain spaces. Avoid dark, fuzzy, or slippery yarns for learning.

Use a 5.0 mm or 5.5 mm ergonomic hook. The slightly larger size creates more defined spaces, which helps you identify where to place the next stitches.

You will also need scissors and a blunt-tipped yarn needle for weaving in ends. Stitch markers are optional but helpful for marking the start of a round.

Gauge is not critical for a practice square, but if you want squares to be uniform later for a blanket, keep your tension consistent and use the same hook throughout.

Understanding the Structure

A classic granny square has four sides and four corners.

• Each side is made from one or more clusters of 3 double crochets.
• Each corner is made from (3 double crochets, chain 2, 3 double crochets) worked into the same space.
• Chain-1 spaces separate the clusters along the sides.

The square grows outward from the center. Each round adds one additional 3-double-crochet cluster per side. The pattern is the same every round; only the number of side clusters increases.

Step 1: Make the Center Ring

There are two reliable ways to start. Choose the one you find easier.

Method A – Chain Ring, easiest for beginners: Chain 4. Insert hook into first chain you made, yarn over, pull through both the stitch and the loop on your hook to make a slip stitch. You now have a small ring. This ring is the center of your square.

Method B – Magic Ring, creates a tighter center: Make a loop with yarn over your fingers, insert hook into loop, pull up a loop, chain 3. Work the first round into the loop, then pull tail to close. If the magic ring is frustrating, use Method A; you can tighten the center later when weaving in the tail.

Step 2: Work Round 1 – Four Clusters to Form the Base

This round creates the foundation of four sides.

1. Chain 3. This counts as your first double crochet.
2. Into the center ring, work 2 dc. You now have a cluster of 3 dc counting the chain-3.
3. Chain 2, this forms your first corner space.
4. Work 3 dc into ring, chain 2. Repeat two more times, so you have four groups of 3 dc separated by chain-2 spaces.
5. After the last chain 2, join with a slip stitch to the top of the starting chain-3. You should see 4 clusters and 4 chain-2 corner spaces.

Pull gently on the tail to close any hole in the center if you used the chain ring method, but do not pull so hard that the work puckers.

Step 3: Work Round 2 – Make the Corners and Learn Side Spaces

You will now work into the chain spaces, not into individual stitches. This is the key difference from row-based crochet.

1. Slip stitch into the next chain-2 corner space. Slip stitching into the space positions you to start the next round in a corner.
2. Chain 3, 2 dc, chain 2, 3 dc all into the same corner space. You have made your first corner.
3. Chain 1, this is the side space between corners.
4. Into the next corner space, work (3 dc, chain 2, 3 dc). Chain 1.
5. Repeat step 4 for the remaining two corners, with chain 1 between each.
6. After the last chain 1, slip stitch to the top of the starting chain-3 to join.

You should now have 8 clusters: 2 per side counting corners as 2 clusters, and 4 corner chain-2 spaces plus 4 chain-1 side spaces.

Take a moment to identify the corners. They each have a chain-2 gap in the middle. The side spaces have a smaller chain-1 gap.

Step 4: Work Round 3 – The Repeating Pattern Emerges

From this round forward, the logic is consistent.

1. Slip stitch into the next corner chain-2 space.
2. Chain 3, 2 dc, chain 2, 3 dc into the same corner space. Chain 1.
3. Work 3 dc into the next chain-1 side space. Chain 1.
4. Into the next corner space, work (3 dc, chain 2, 3 dc). Chain 1.
5. Continue around: 3 dc into each side chain-1 space with chain 1 between, and (3 dc, chain 2, 3 dc) with chain 1 after each corner.

Join with a slip stitch to the top of chain-3. Each side now has 2 clusters between corners instead of 1.

Step 5: Continue Growing the Square

Each additional round adds one more side cluster per side.

The repeat for any round after Round 2 is:

Slip stitch into corner space, (chain 3, 2 dc, chain 2, 3 dc) in same corner, chain 1, 3 dc in next chain-1 space, chain 1, (3 dc, chain 2, 3 dc) in next corner space repeat from * around, chain 1 after last side cluster, slip stitch to join.

Stop when your square reaches the desired size. For a practice coaster, 3 to 4 rounds is enough. For a blanket square, 5 to 8 rounds is common.

Changing Colors

One of the most attractive features of a granny square is color change.

To change color at the end of a round: Complete the last chain 1 of the round, but do not join yet. On the slip stitch that joins, pull through with the new color instead of the old color. Cut the old color, leaving a 6-inch tail. Continue with new color.

Alternatively, fasten off after each round, cut yarn, and join new color with a slip stitch in any corner space to begin the next round. This creates more tails to weave in but gives very clean color transitions.

When weaving in tails, use your yarn needle and work the tail through the back of stitches of the same color for at least 2 inches, change direction, and go another inch before trimming. This prevents tails from working loose.

Common Problems and How to Fix Them

Square is turning into a circle or bowl: You may be adding extra chain spaces or missing corner chain-2 spaces. Each corner must have chain 2. Each side space must have chain 1. Count your clusters per side after each round.

Square is curling or ruffling: Tension may be too tight or too loose. If curling up like a bowl, your tension is too tight or you are missing chain spaces. If ruffling like a lettuce leaf, you are adding extra clusters or chain spaces.

Corners are not square: Make sure you work (3 dc, chain 2, 3 dc) into each corner, not just 3 dc. The chain-2 creates the 90-degree turn. Also ensure your chain-2 is not too tight. If corners look pinched, chain 3 in corners instead of chain 2 for a looser corner.

Hole in the middle is too large: When using the chain-4 ring, the hole is naturally larger than a magic ring. After Round 1, use the starting tail to cinch the ring by weaving it through the base of the stitches and pulling gently, then secure it.

Losing track of where you are: Place a stitch marker in the starting chain-3 at the beginning of each round. Always join to that marked stitch. Count clusters per side after joining: Round 1 has 1 cluster per side, Round 2 has 2 clusters per side counting the corner halves as one side cluster, Round 3 has 3, and so on.

Finishing and Blocking

After your last round, cut yarn leaving a 6-inch tail, yarn over and pull tail completely through the loop on your hook to fasten off. Weave in all tails.

Blocking helps the square lay flat and become truly square, especially for joining later.

For acrylic: Pin the square to a blocking board or towel, measuring each side to ensure equality, lightly steam with an iron held an inch above the fabric without touching, let cool completely.

For cotton: Wet the square, gently squeeze out excess water, pin to shape and let air dry.

Granny squares become much easier after the second round because the pattern is repetitive. Focus on working into spaces rather than stitches, maintaining chain-2 corners and chain-1 side spaces, and joining accurately. Once you can make a consistent 4-round square with straight edges and square corners, you have a motif that can be repeated in any color combination and joined into countless home projects.
