This is the first hat I improvised, and I'm delighted with how it turned out. I wanted to echo the moss stitch used in the center of the scarf, which I knit with a cable pattern from Barbara Walker's Fourth Treasury of Knitting Patterns, "Cable no. 8."
The yarn is wonderful, Fiber Creations Dyed Wool, from sheep raised within an hour of where I live. I bought at Meridian Jacobs Meet the Sheep 2008, which was absolutely delightful. And the hat and scarf are so warm.
