I am having a problem understanding this part of a pattern for a knitted vest called “Sushi” by Martin Storey. http://www.ravelry.com/patterns/library/sushi-9
Shape shoulders and back neck
[B]Next row (RS):[/B] Cast off 4 sts, knit until there are 8 stitches on right needle, turn and leave rem stitches on a holder.
Work each side of neck separately.
Could anyone tell me what it means to work each side separately.
Thank you in advance.
