I am writing pattern for stretchy tank top. The stitch pattern is four rows: one is all yo, k, the even rows are all purl back, third row is all skp.
My question is describing the shaping rows (hips, armhole, shoulder, neck shaping). Depending on which row you are on while knitting in pattern you have half/double the number of stitches. How would I describe decrease? Both options with an explanation?
