Row 1: (RS) 1tr in third ch from hook, 1tr in each of next 23 (33, 43, 53) ch, 2tr in each of next 2 ch, [1ch, miss 1ch, 1tr in next ch] six times, 1ch, miss 1ch, [1tr, miss 1ch] five times, 1ch, miss 1ch, [1tr, miss 1ch, 1ch] six times, 2tr in each of next 2ch, 1tr in each of remaining 25 (35, 45, 55)ch, turn – 89 (109, 129, 149) sts.
Row 3: (RS) 3ch (counts as 1tr)…
Please note that at the end of Row 2 and subsequent WS rows you work the last dc in the 3ch of Row 1 or 3. This should give you the correct number of stitches. On RS rows, make 3ch to count as 1tr, do not work into the stitch at the base of the chain but instead 1tr in each of the next 25/35/45/55 sts.
