My opinion, save and get a good stave. Trade for it, or buy one. The better the material you start with the greater the likelyhood you end up with a working, hunting weight bow. Osage, hickory, elm, hackberry, or one of the other proven bow woods. Starting with quality wood can allow you to spring forward a long ways. You can avoid some of the common issues that many newbies get caught up in. Too short, narrow, rotten, grain run off, bad knots, poor specimen in general, etc etc. You will never make a silk purse from a sows ear.
