Jacob (or anyone, for that matter), what would you conisder to be the best source to find out how to do "bread art" or "bread sculpting" (designs, animals, etc.) that would create an edible product?  I see quite a few things on the Internet, but am hoping someone here could help narrow things down and help me to find a good tutorial, book, or even a course (although I can't afford much right now).

Any ideas?  Thanks!
