\nTip: Always pull your puff and bobble stitches tight at the top — this keeps the sunburst center looking clean and defined.

How to Crochet the Classic Sunburst Granny Square Step by Step
The classic sunburst granny square works up in 4 rounds. Round 1 creates the center, Round 2 adds puff stitches for the first layer of sun rays, Round 3 builds bobble stitches for bold sunbeams, and Round 4 converts the circle into a perfect square.
Round 1: Make the Center of the Sunburst
The center of the classic sunburst granny square is a simple circle of 16 double crochet stitches worked into a magic ring. This round creates the solid core that the sunburst will radiate from.
Pattern: ch3 (counts as dc) + 15 dc in a magic ring, sl st to the top of ch3, fasten off. You should have 16 dc total.
- Start with a magic ring
- ch3 as your standing stitch (this counts as 1 dc)
- Work 15 dc into the ring
- Pull the magic ring tail tightly to close the center
- Slip stitch to the top of the first ch3, fasten off
If you are new to the magic ring technique, our magic circle crochet guide covers it in detail. A tight magic ring is essential for a clean center in your classic sunburst granny square.
Round 2: First Layer of Sun Rays with Puff Stitches
Round 2 introduces the puff stitch, which creates the soft, textured first layer of sun rays around your center. Each puff stitch is made from 3 incomplete half double crochet stitches pulled together.
Pattern: Join new yarn in any stitch, ch1 (counts as incomplete hdc) + 2 more incomplete hdc, yo and pull through all loops (3-hdc-puff made), ch1. [3-hdc-puff + ch1 in next stitch] repeat 15 times. Sl st to top of first puff, fasten off.
Key tip: Hold all the loops on your hook together at the base before pulling through. Loose puff stitches are the most common mistake beginners make with the classic sunburst granny square.
Round 3: Bobble Stitches for Bold Sunbeams
Round 3 adds bobble stitches (4-dc-bo) in each chain space from Round 2. These bobbles are larger and bolder than the puff stitches, creating that dramatic sunburst effect.
Pattern: Join new yarn in any ch-sp, ch2 (counts as incomplete dc) + 3 more incomplete dc, yo and pull through all 5 loops (4-dc-bo made), ch2. [4-dc-bo + ch2 in next ch-sp] repeat 15 times. Sl st to top of first bobble, fasten off.
This round is where the classic sunburst granny square really starts to look like sunshine. The combination of the small puff rays from Round 2 and the larger bobble rays from Round 3 creates beautiful layered dimension.
Round 4: Turning the Sunburst into a Square
The final round converts your circular sunburst into a perfect square shape using a combination of dc, hdc, and treble crochet stitches. The treble clusters at each corner create the square corners.
