As seen in
Plush Sleuth :) Or you can look at the two measly pictures in this post.
( The best problem sleuth in the entire tri-couch area )( Crochet your own sleuth )That should be all :) Please comment if you have any questions or want clarification or whatever.
Edit: [Dec 27 2011] I've edited PS's hat slightly to make it more accurate. That'll teach me not to crochet without getting proper reference pictures. I've also fixed up some instructions a bit to hopefully make them clearer. Pictures of Sleuth 2.0 coming eventually.
