I adapted a (free!) pattern for a knit lobster by Molly Lincoln at http://dirigo.wordpress.com/2007/12/17/free-pattern-toy-lobster/ to look a little more like my blue crayfish.
This is one of the best lobster patterns I have come across and have had it in my queue of projects for awhile. When I recently acquired a (real) blue crayfish, I just had to knit this immediately. I decided to modify it a little bit to make it more like my crayfish, not because I thought the pattern needed any changing on its own.
