The Whirlwind Dahlia Pinwheel: A Free Crochet Pattern for a Textured, 3D Floral Motif

Introducing the Whirlwind Dahlia Pinwheel

Create a stunning, dimensional pinwheel flower that mimics the intricate layers of a dahlia, perfect for embellishing hats, bags, or creating a unique wall hanging. This pattern uses a clever combination of post stitches and color changes to build a mesmerizing spiral of petals. The result is a textured, 3D floral motif that looks far more complex than it actually is—a true showstopper for any handmade project.

Materials Needed

• Yarn: Worsted weight (#4) cotton or acrylic yarn in three colors:
  • Color A (center): Deep burgundy (approx. 10 yards)
  • Color B (mid-petals): Burnt orange (approx. 10 yards)
  • Color C (outer petals): Golden yellow (approx. 10 yards)
  Approximately 30 yards total.
• Hook: 5.0 mm (H-8) crochet hook
• Other: Stitch marker, yarn needle for weaving ends
• Gauge: First 3 rounds = 2 inches in diameter. Exact gauge is not critical for this motif.

Step-by-Step Instructions

Notes: Work in continuous rounds (spiral) unless otherwise stated. Do not join at the end of rounds unless specified. Use a stitch marker to keep track of the first stitch of each round.

Round 1 (Color A – Center)

Make a magic ring. Ch 1 (does not count as a stitch). Work 6 single crochet (sc) into the ring. Pull ring tight to close. (6 stitches)

Round 2 (Color A)

Work 2 sc in each stitch around. (12 stitches)

Round 3 (Color A)

*Sc in next stitch, 2 sc in next stitch; repeat from * around. (18 stitches)

Round 4 (Color A)

*Sc in next 2 stitches, 2 sc in next stitch; repeat from * around. (24 stitches). Fasten off Color A.

Round 5 (Color B – First Petal Layer)

Join Color B with a slip stitch (sl st) in any sc from Round 4. Ch 1. *Working in the front loops only (FLO) of the previous round, sc in next stitch, half double crochet (hdc) in next stitch, double crochet (dc) in next stitch, treble crochet (tr) in next stitch, dc in next stitch, hdc in next stitch, sc in next stitch; repeat from * around. This creates the first layer of petals. You will have 6 petals. Sl st to first sc to join. Fasten off Color B. (24 stitches per petal layer, but each petal uses 6 stitches)

Round 6 (Color C – Base for Outer Petals)

Working in the remaining back loops (BLO) of Round 4, join Color C with a sl st in any stitch. Ch 1. *Sc in next 2 stitches, 2 sc in next stitch; repeat from * around. (32 stitches)

Round 7 (Color C – Second Petal Layer)

Ch 1. *Working in FLO of Round 6, sc in next stitch, hdc in next stitch, dc in next 2 stitches, tr in next 2 stitches, dc in next 2 stitches, hdc in next stitch, sc in next stitch; repeat from * around. This creates a second, larger layer of petals. You will have 8 petals. Sl st to first sc to join. Fasten off Color C.

Finishing

Weave in all ends using a yarn needle. Gently shape the petals by curling them slightly upward with your fingers. The pinwheel effect is created by the alternating front loop petals and the spiral growth of the rounds. Your Whirlwind Dahlia Pinwheel is complete!
