I need help I am trying to wrap my brain around a rep row and the row goes like this. K1.P1.K1.P1. REP fromto last 2 sts. P1.K1 Rep from ** to**until 9 sts remain. But how do I do that if i don’t tog the stitches or drop stitches

Not really enough information. Can you give us a pattern name and link please? Even if it’s paid for it helps to see it. (Don’t post t he pattern here)
