Step-by-Step Instructions
Center Circle
- Start: Make a magic ring or ch 4, sl st into first ch to form a ring.
- Round 1: Ch 3 (counts as dc), work 11 dc into the ring. Sl st to join. (Total: 12 dc)
Half-Circle Rows (Refer to color changes between rows for added effect)
2:
- Ch 3 (counts as 1 dc),
- Ch 2, dc in next stitch, ch 2 – repeat from * to end of row.
- You’ll create a dc separated by ch-2 spaces across the row.
3:
- Ch 3 (counts as dc),
- Ch 4, skip 2 sts, dc in next st, ch 4 – repeat across.
- This creates wider mesh-like spacing.
4:
- Ch 3 (counts as dc),
- Work 1 dc in next 4 stitches,
- Ch 1, 4 dc in next 4 sts – repeat this cluster and ch-1 spacing across.
- End with 5 dc (for symmetry).
5:
- Ch 3 (counts as dc),
- Dc in every stitch and space across to fill the row solidly.
- No chaining or skipping here.
6:
- Ch 3 (counts as dc), dc in same stitch (2 dc total in 1 st),
- Ch 1, skip 1 stitch, 2 dc in next 2 stitches,
- Ch 1, skip 1 st, (dc, ch 1, dc) in same stitch,
- Repeat pattern till end.
This row adds gentle fans and lacy spacing.
7:
- Ch 3, dc in same st,
- Ch 2, skip 1 st, work 2 dc together (dc2tog) over next 2 sts (a decrease)
- Ch 2, skip 1, work 4 dc in the same st,
- Ch 2, skip 1, dc2tog again…
- Continue repeating the sequence to build the rhythm of fans and valleys.
8:
- Dc in next stitch
- Ch 3, skip 2 stitches
- Dc in next stitch
- Ch 3, 1 dc in each of the next 4 stitches
- Ch 3, skip 3 stitches
- Dc in next stitch
Repeat this pattern until the end of the row.
This creates beautiful arched spacing and blocks across the fan.
9:
- Ch 3 (counts as dc)
- Ch 4, skip 2 stitches
- Sc in next stitch
- Ch 4, skip 2 stitches
- Dc, Ch 1, Dc in the same stitch (creates a V-stitch)
- Ch 4, skip 2 stitches
- Sc in next stitch
- Ch 4, skip 2 stitches
- Dc in next 2 stitches
Repeat this sequence across the row.
This creates a nice open lace structure with alternating V-stitches, single crochets, and 2-dc clusters with ch-4 arches in between—just as shown in the chart!

A: Absolutely. Continue the pattern symmetrically to complete the circle.
Q: Is it beginner-friendly?
A: Intermediate crocheters will enjoy it best, but adventurous beginners can try with guidance from the diagram.
