I’m still a bit confused. Does that mean that if it’s a RS row and it is one of the decrease rows (row 3, row 7) then I would follow what it already says for RS rows but on other RS rows when it is not a decrease row (row 1, row 5) I would omit the ssk? Would that also mean that on the WS row when I am decreasing I add in the ssk at the neck edge?
On the rows in between, for the knit rows, knit to the seed stitch border.
On the purl rows, decrease at the neck edge, but do a ssp at the neck edge after the seed stitch.
