i recently bought the book "The Sock Knitter's Handbook" by Schurch and Parrot. This weekend i decided to try one of their ribbing for the leg of a child's sock. The facet rib is knit in multiples of 2 sts. Rnds 1 and 2:knit Rnd 3:k1, sl 1 rep across row. Rnd 4: P1, sl 1 repeat across row. Keep repeating this pattern for as long as you need. I really like the way it looks. The book has lots of ribbings that i am excited to try!
