Need help on shaping armhole!! pls
I am still quite a beginner when it comes to knitting. I have made blankets but I really want to try a baby sweater. Can someone please explain this sentence to me:
Shape armholes: Cast off 5 (6-8-8) sts beg next 2 rows. 43 (45-47-49) sts.
Cont even until armhole measures 4½ (5-5¼-5½) ins [11.5 (12.5-13-14) cm], ending with RS facing for next row. Cast off.
Thank you so much!
