Rnd 1: ch 3 (counts as first dc), 2 dc in ring, (ch 3, 3 dc in ring) 5 times, ch 3, sl st in top of beginning ch-3 of this round.
Rnd 2: sl st in ea of next 2 dc, sl st in ch-3 sp, ch 3 (counts as first dc), (dc, ch 1, 2 dc) in same ch-3 sp, * ch 2, skip next 3 dc, (2 dc, ch 1, 2 dc) in next ch-3 sp **, repeat the directions between * and ** 4 more times, then ch 2, skip next 3 dc, sl st in beginning ch-3 of this rnd. End off. Weave in ends.
