That sounds like fun. I too did some leather work back some years ago. I still have a few tools; punches, sewing awls, needles, snap and rivet dies, etc. I did a practice seat cover on the last bike I built but used cheap vinyl. It came out okay but I'd really like to do one in real leather and do some burning similar to the saddle you pictured.
