Sunflower granny squares can begin as a sunburst, use a popcorn stitch petal round, turn a puff stitch flower into a square, or build 3D petals that stand off the surface. These six original patterns list different finished measurements and stitch approaches.
3D petal rounds hold their shape best with a hook you are already used to, since the tension changes as you add rounds.
Sunflower granny square patterns to explore
1. Sunburst Granny Square
Sarah Stearns at Sarah Maker presents a beginner intermediate four color square measuring about five inches. The four rounds keep the color changes simple, making it a good starting motif before trying the more advanced puff stitch or 3D versions further down this list. It’s worked in worsted-weight (#4) yarn with an H (5mm) hook, using puff and cluster stitches across the rounds – Round 1 alone builds to 16 double crochets.
2. Popcorn Stitch Sunflower Square
Carmen at Annie Design Crochet uses a popcorn stitch petal round. With the stated yarn, the square measures about 4.25 inches. This popcorn stitch gives the petals more texture and dimension than a flat granny round, without the fully raised 3D petals used in Melissa Hassler’s version below. The designer’s own materials list calls for King Cole Big Value DK with a 4.5mm hook, though worsted weight with a 5.5mm (I) hook works as a substitute.
3. Puff Stitch Sunflower Square
Tonya Bush at Nana’s Crafty Home starts with a puff stitch flower and squares it off. The finished square measures about six by six inches after blocking, larger than Sarah Stearns’s or Carmen’s versions, so plan your motif count accordingly if mixing sizes in one blanket. It’s worked in Brava Worsted (WeCrochet), a #4 medium-weight acrylic, on a 5.5mm (I) hook.
4. 3D Sunburst Sunflower Square
Melissa Hassler at Lovable Loops builds 3D sunburst petals that stand off the surface rather than lying flat, in worsted yarn on a 5mm hook. It finishes at 7.25 inches, the largest square on this list, and the raised petals add noticeably more texture than the flatter designs above.
5. Bobble & Puff Sunflower Square
Alyssia Stacey-Orchard at Alyssia Creates combines puff and bobble stitches across four colors, worked on a 4mm hook. At about 4 by 4 inches, it’s closest in size to Carmen’s popcorn stitch version, though the mixed stitch pattern gives it a noticeably different surface texture.
6. Sunflower Granny Square
Menucha at Moms and Crafters crochets a 12-double-crochet center ring, then works petals in treble crochet clusters joined by chain-3 gaps, before adding a double crochet and treble crochet border through those same gaps to square off the motif.
