Note: Round 2 is joining round. See “assembly” for instructions on working joining of squares 2–35 while working Round 2 of border.

Round 1: Starting in next ch-space, sc evenly around entire piece working 2 sc in each remaining ch-space on Row 10, sc in each remaining dc on Row 10, 2 sc around post of each dc and in turning ch-spaces along edges of rows, sc in each st on Row 11, (sc, ch 2, sc) in each of 3 corner sts or spaces on Rows 10 and 11 (corner st at beginning of Row 10 is 3rd ch of turning ch-5) and (2 sc, ch 2, 2 sc) in beginning ring, ending with sc in slip st – 4 corner ch-2 spaces and 92 sc (23 sc on each side between corner ch-2 spaces). Join with slip st in first sc.
Round 2: *Ch 4, skip next 2 sc, slip st in next sc; repeat from * around working (slip st, ch 4, slip st) in each corner ch-2 space – 36 ch-4 spaces. Join with slip st in joining slip st. Fasten off. 

See Construction Diagram below. Join squares into 5 columns with 7 squares in each column. In columns 1, 3, and 5, fans should point down and to the right. In columns 2 and 4, fans should point up and to the right. Join on 1 or 2 sides as necessary while working Round 2 of border. To join ch-4 spaces on 1 side of square, continuing in pattern st, ch 2, drop loop, draw loop under to over through corresponding ch-4 space on adjacent square, ch 2 and continue in pattern st. When joining 2 sides of square where corner of square meets corner of 3 adjacent squares, ch 2, drop loop, draw loop under to over through corresponding corner ch-4 space on first adjacent square, ch 1, drop loop, skip corner ch-4 space on 2nd adjacent square, draw loop under to over through corresponding corner ch-4 space on 3rd adjacent square, ch 2 and continue in pattern st.  

Round 1: With right side facing, join with slip st in any corner ch-4 space, ch 4, slip st in same ch-space as joining; *ch 4, slip st in next ch-4 space; repeat from * around, working (ch 4, slip st in each of next 2 joined corner ch-4 spaces) at each joining seam of squares and (ch 4, slip st) twice in each of 4 corner ch-4 spaces – 220 ch-4 spaces. Ch 4, join with slip st in joining slip st.
Round 2: Slip st in next corner ch-4 space, ch 3 (counts as dc), work 6 dc in same corner ch-4 space (beginning corner shell made), sc in next ch-4 space; *5 dc in next ch-4 space (shell made), sc in next ch-4 space; repeat from * around, working [7 dc in corner ch-4 space (corner shell made), sc in next ch-4 space] at each remaining corner – 106 shells and 4 corner shells. Join with slip st in 3rd ch of beginning ch-3.
Round 3: Slip st in next 3 dc, ch 5 (counts as dc and ch-2 space), dc in same dc as last slip st; ch 1, skip next dc, dc in next dc, ch 1, skip next dc, dc in next sc, work [ch 1, skip next dc, dc in next dc (2nd dc of shell), ch 2, skip next dc, dc in next dc (4th dc of shell), ch 1, skip next dc, dc in next sc] in each shell around and [ch 1, skip next dc, dc in next dc (2nd dc of shell), ch 1, skip next dc, (dc, ch 2, dc) in next dc (center dc of shell), ch 1, skip next dc, dc in next dc (6th dc of shell), ch 1, skip next dc, dc in next sc] in each corner shell. Join with slip st in 3rd ch of beginning ch-5.
Round 4: Ch 3 (counts as dc), work 5 dc in each corner ch-2 space, 3 dc in each ch-2 space along sides, dc in each ch-1 space and in each dc around. Join with slip st in 3rd ch of beginning ch-3.
Round 5: Ch 1, sc in same ch as joining; *ch 1, skip next dc, [(sc, ch 2, sc) in next dc] 3 times, ch 1, skip next dc, sc in next dc; [ch 1, skip next dc, sc in next dc] 3 times*; **ch 1, skip next dc, (sc, ch 2, sc) in next dc (center dc of 3 dc worked in ch-2 space along side), [ch 1, skip next dc, sc in next dc] 3 times**; repeat from ** to ** along sides, ending with one additional repeat of [ch 1, skip next dc, sc in next dc] before corners; repeat from * to * in corners, ending with ch 1, skip next dc, join with slip st in first sc.
Round 6: Ch 1, (sc, ch 3, sc) in same sc as joining; *ch 1, (sc, ch 3, sc) in first ch-2 space in corner, ch 1, (sc, ch 4, sc) in 2nd ch-2 space in corner, ch 1, (sc, ch 3, sc) in 3rd ch-2 space in corner, ch 1, sk next sc, (sc, ch 3, sc) in next sc, ch 3, skip next sc, slip st in next sc*; **ch 3, skip next 2 sc, (sc, ch 3, sc) in next ch-2 space, ch 3, skip next 2 sc, slip st in next sc**; repeat from ** to ** along sides, ending with [ch 3, sk next sc, (sc, ch 3, sc) in next sc] before each corner (except beginning corner) and repeating from * to * in each rem corner. Ch 3, join with sl st in first sc. Fasten off.
