This pattern has two options: - knitting it as a "cocoon", by knitting in the round - making it as a lap blanket, open in the back, by knitting back and forth Ladies size small, medium, large, XL and XXL are given. This "scales" stitch pattern is just perfect, and I can't emphasize enough how easy this stitch is to create. A REALLY fun project! Materials needed: 29-inch long circular needle, US 11 (8mm) Light worsted yarn (known as DK or 8-ply in some countries), 30 to 36 ounces. Two strands are held together, but some knitters liked their result using one strand of chunky. If knitting yours in the round, you will also need a 16-inch needle and a set of dpn's.
