Nice, how this came together! I made a three piece once, too. Used the same inserts for the screws, just mine were excentered, so string alignment was adjustable. Took them out of old furniture.
Great, when things get reused! Also the zipper is an cool idea! Would be even better, when it look alike the osage would be behind.
This are the kind of bows I love to see here, a lot of good ideas!
Congrats! B2W
