(Note: In all chain stitches, work behind the vertical bar.)
Step 1: start with the foundation chain: 23ch. Then in 2nd st from hook: (2sc in next st)*2 times, 2sc, (2sc in next st)*2 times, 10sc, (2sc in next st)*2 times, 2sc, (2sc in next st)*2 times.
Step 2: turn, 2ch, 2hdc, 2hdc in one st, 1hdc, 2sc, 1hdc, 2hdc in one st, 4hdc, (2hdc in one st)*2 times, 2hdc, (2hdc in one st)*2 times, 4hdc, 2hdc in one st, 1hdc, 2sc, 1hdc, 2hdc in one st, 2hdc.
Step 3: turn, 2ch, 2hdc in one st, 4hdc, (2hdc in one st)*2 times, 4hdc, 2hdc in one st, (1hdc, 2hdc in one st)*2 times, 6hdc, (2hdc in one st, 1hdc)*2 times, 2hdc in one st, 4hdc, (2hdc in one st)*2 times, 4hdc, 2hdc in one st. 1ch.
