How to Knit - SSP - Slip Slip Purl Continental Style. This is a video tutorial on how to work an SSP. An SSP leans to the left just as an SSK, while a P2tog leans to the right just as a K2tog. Slip the first stitch as if to knit, slip the second stitch as if to knit, then purl them together through the back loops. This is demonstrated using the Continental Knitting method.
