This pattern I am working on is baby booties, the section in the pattern I am up to tells me K9,p2,k2,p2, then leave the remaining sts unworked (there is 24sts):aww: . Next step says to Slip all sts with yarn in front. I don't understand what it means to leave the remaining sts then slip all sts? I understand 'yarn in front' but that's all. Hope this is not confusing??
