Now that I have a knack for making hats, experimentation is the thing. Remember the yarn I received as a door prize at the Pittsburgh Knit and Crochet Festival? It is in various shades of blue, so another try with wave action seemed to be in order. This time, the waves are more random, which made the hat more of a challenge. But the hat fits, and is warmer than I would have thought. With the scarf, you'll be toasty until the temp gets down into the thirties or so.
Here you can see the waves a little better.
