I, too, have always wanted to make my own saddle. For over 20 years it's been a "plan", but I've never had the time or money to do it. In preparation, many years ago I bought two saddle patterns that can be modified for pleasure and roping saddles. I planned on combining my favorite parts of both into one saddle. Somewhere here in my house are the two packages. If I can find them, I can get them reproduced and you can have copies. Before doing that, of course, I would send you the pictures of the saddles to see if they were anythin you were interested in.
