Stitch Guide (Abbreviations)
- ch: chain
- sc: single crochet
- dc: double crochet
- sl st: slip stitch
- sp(s): space(s)
- Beg Cluster: (2 dc, ch 2, 2 dc) in same sp
Step-by-Step Instructions
Center & Foundation
- Start: Chain 5, join with slip stitch to form a ring.
- Round 1: Ch 3 (counts as first dc), work 11 dc into ring, join with sl st to top of beg ch-3. (12 dc total)
- Round 2: Ch 4 (counts as dc + ch 1), *dc in next dc, ch 1; repeat from * around, join with sl st to 3rd ch of beg ch-4. (*12 ch-1 sps*)
Building the Texture
- Round 3: Sl st into first ch-1 sp, ch 3, 2 dc in same sp, *3 dc in next ch-1 sp; repeat from * around, join. (*36 dc*)
- Round 4: Ch 3, dc in next dc, *ch 2, skip 1 dc, dc in next 2 dc; repeat from * around, ending with ch 2, skip last dc, join. (*12 ch-2 sps*)
- Round 5: Ch 3, dc in next dc, *(2 dc, ch 2, 2 dc) in next ch-2 sp (Cluster made), dc in next 2 dc; repeat from * around, ending with Cluster in last ch-2 sp, join.
Continuing the Pattern
- Rounds 6–10: Follow the established pattern, increasing the number of dc between clusters by 1 each round:
- Round 6: 2 dc between clusters
- Round 7: 3 dc between clusters
- …
- Round 10: 6 dc between clusters
- Beyond Round 10: Continue increasing by 1 dc between clusters each round until the afghan measures 33″ (84 cm) from center to edge (full diameter will be ~66″)
Pro Tips for Success
- Mark your rounds: Use a stitch marker in the first stitch of each round to avoid losing your place.
- Keep tension even: The skipped stitches can pull tighter—relax your grip!
- Blocking is key: Once finished, lightly steam-block to open up the lace-like clusters.
Finishing Touches
Weave in all ends securely. For extra durability, consider adding a simple scalloped border (optional):
- Join yarn to any cluster space, ch 1.
- Work *[sc, hdc, 3 dc, hdc, sc] in each ch-2 sp* around.
- Fasten off and weave in ends.
