Go to Garage Sales to find cheap fur coats. I bought one for a dollar. Turned out to be chinchilla. World's most expensive, yet cheap, string silencers. Every time you or your friends harvest a deer, take all the legs from the knee down. Lot's of good sinew gets thrown away. Got friends that hunt waterfowl? Have em save the wings off geese. Goose feathers are nice on arrows. Go to your local high school wood shop. Ask to go through the scrap barrel. Small pieces of walnut, maple, oak, cherry, etc make good accent strips in composite bows. Also, while at garage sales or flea markets, look for leather jackets, use leather for handles. You can even make a nice quiver out of the sleeves.
