This version, made from just under two skeins of natural black Eco-wool (about $30 total) on size 10 1/2 needles, is cheaper and more versatile than the self-striping one shown in the book. I hope you can see well enough despite the hard-to-photograph black.
Hudson knits up fairly quickly, and can easily be modified to be worked mostly in the round for those who hate seaming. I'm working on a mauve one now for a birthday present, and am knitting the body all in one piece this time, which is working out great. Thanks for looking!
