I got my first batch of supplies from Old Master Crafters but, there are several others out there. They had all the supplies (epoxy, laminates, wedges, etc.) as well as some basic blue prints for various bows. Check them out and ask some questions then order a few pieces for patterns.

Go conservative at first. My first had a beautiful burled walnut riser, laminated with cherry and bubinga, and maple with walnut wedges and clear glass limbs. Beautiful bow - pulled 97# at 28" though. Looks good on the wall.
