Hi! I am a beginning knitter and want to make spirals for a golf head cover. the pattern says: "Cast on 15 sts, (I've done), Row 1: Knit into front, back and front of each stitch across. Row 2: Bind off. It sounds simple, but can anyone explain? It just seems like a jumbled mess! How do you knit into front, back and front of a single stitch?
