The two basic stitches in knitting are the Knit Stitch and the Purl Stitch. Once you know how to do both of them you can put them together to make RIBBING. RIBBING is usually, but not always, used at the bottom of a garment, as well as at the cuffs and at the neck. It's also a good stitch to use when you want both sides of the fabric to look the same like for a scarf or a blanket. RIBBING is usually K2 P2 (knit 2 stitches, purl 2 stitches) but it could be K1 K1 (knit 1 stitch, purl 1 stitch)...
