It state row 1 is the wrong side (WS) so Row 2 is the right side. To me it’s written wrong because it says cast on so many stitch and Purl the Row 1 on the RIGHT side.
I am very bad at having to decrease so many stitches so the use the this website: www.thedietdiary.com/knittingfiend/tools/EvenlySpace.html
With smaller needles, cast on 65(71-77-81-87-93) sts.
Purl 1 row on RS.
Ribbing: Row 1 (WS): P1, * k1, p1, rep from * across.
Row 2: K1, * p1, k1, rep from * across. Rep these 2 rows until piece measures 1½” from beg, end on RS. Change to larger needles and p the next row, dec 22(24-28-28-30-32) sts across – 43(47-49-53-57-61) sts. Work even in St st until piece measures 7(7½-8-8½-9-9½)” from beg, end on WS. Work even in Pat St until piece measures 9½(10-10½-11-11½-12)” from beg, end on WS. Mark beg and end of last row for beg of armholes. Work even in Pat St until armholes measure 4½(5-5-5½-5½-6)”, end on WS. Bind off.
