new to knitting
I have a sweater and I am to the neck shaping and it says row 1: For first shoulder, work in pattern across 21 sts; for the neck edge, with separate ball of yarn, bind off 46 for second shoulder, work in pattern across last 21 sts. Next rows: working both sides at same time with separate balls of yarn, work in pattern until piece measures 20", from cast on, ending after p row. Bind off each shoulder loosely. First of all am I suppose to knit the way I have for the last 16" prior? Then the are the 46 sts that are in the middle?
