I used almost 2 skeins of double stranded Mountain Colors Bearfoot in Pheasant colorway on size 10 needles, 32 stitches. I'm a tight knitter so others might need a smaller needle. The baby cable rib is an old stitch pattern, I think, and I first saw it in Sensational Knitted Socks and also in Barbara Walker's treasury.I added garter stitch borders and ends. It was fun to knit--not too boring but easy enough to do while watching TV.
