Butch,
I'm not a 'saddle maker' but I've made a saddle and working on another one. If I live long enough and get busy making them and learning more then maybe - just maybe, I can call myself one before I die.
I learned from a true saddle maker that has been doing it all his life - so far. I don't think any book can beat that. It is good to have a book or two for reference. I think that you will need that when you're sitting in your shop by yourself making one. My favorite two are the Stohlman Encyclopedia set and the 'Saddlemaker's Shop Manual' by Harry G. Adams Jr.
