Since most of us benefit from knowing what different types of wood looks like, I was wondering iv you've ever heard of this site?
http://www.hobbithouseinc.com/personal/woodpics/ They don't sell anything, and the page layout is very basic, but it has a tremendous amount of pictures of different woods, and of the variations in each woodtype! 700 different woods, total 20k pictures.
I hope the posting of this link isn't illegal, and If so, I will remove it at once!
I just think it might be helpful to those who are purchasing new bows (or old) or maybe make wood products..
Anyways, enjoy it
