Question: what does s11 mean in knitting?
Answer: "S11 k1 PSSO" is actually Sl 1, k1, psso or slip 1, k1, pass over. It could be a typepo or the small l just came out looking like 1. You do this by slip the first st of the left needle purlwise, then knit the next st then use the left needle to lift up the slipped st on the right needle over the st just knitted.
