This cowl is inspired by the Great Wave off Kanagawa woodblock print by Hokusai. It begins as a scarf (using a crochet cast-on), and is worked flat with a slipped stitch edge. Once the proper circumference is reached, it is attached on one side as you knit. The reversible wavy texture is seen when the upper corner is folded down. While a cable needle is used, it is for picking up stitches, not for cables. Inspiration also came from Lynne Barr's Reversible Knitting book.
