I've finally gotten to the cap shaping on the sleeve I'm knitting and need some advice on the decreases. The pattern says to decrease one stitch each side for 16 rows. All the decreases up to this point have been on the right (knit) side and I've been using slip-slip-knit (SSK) first and knit-two-together (K2tog) for the second. How do I decrease on the wrong (purl) side? Would it be SSP then P2tog?
