Lace Pattern:
ROW 1: 1 dc in 2nd ch from hook, (miss 2 ch, 3tc in 1 ch, miss 2 ch, 1 dc), repeat to end of row, end in dc.

ROW 2: 2 tc, (miss 2 ch, 1 dc, miss 2 ch, 3 tc in 1 ch), repeat to end of row, end in 2 tc.

CORRECTION: Please note after finishing the sleeves, for the back to match the front exactly an additional 4 rows need to be worked before casting off a half-pattern on each side.

That is, after decreasing 5 patterns each side for the sleeves, work 14 rows (NOT 10) of 22 pattern repeats before decreasing a half-pattern each side. Commence the rest as written.
