My pattern states as follows: I don’t understand how to do this. I have worked to ‘Dec 1 st at neck edge of next 3 rows, ending with RS facing for next row.’ I don’t see why I need to break the yarn when the pattern then says rejoin it. Can someone please explain what I need to do. I now have 15 stitches for the right shoulder and all the remaining stitches on the needle as well.
Shape back neck and shoulders
Next row (RS): Knit until there are
17 [18: 20: 21] sts on right needle K2tog, turn and work on these 18 [19: 21: 22] sts for right shoulder.
Dec 1 st at neck edge of next 3 rows, ending with RS facing for next row.
Break yarn and leave rem 15 [16: 18: 19] sts on a holder.
With RS facing, rejoin yarn to sts from holder, cast off 15 [17: 17: 19] sts, knit to end.
19 [20: 22: 23] sts.
Dec 1 st at neck edge of next 4 rows, ending with WS facing for next row.
Break yarn and leave rem 15 [16: 18: 19] sts on a holder for left shoulder.
