So Don are you burning the Mulberry? How bad are the checks? The only Mulberry I have made from was Red Mulberry from northern Indiana a friend cut from a friend's yard. He removed the bark and sent me a stave. Sat for about a year, then I removed the sap wood. The hardest Sapwood EVER! Thick rings and made a nice little 44 lb. reflexed tips and snake skin backed, by Gary Davis. He used the bow to show how at the 1st. Primitive shoot at Marshall, Michigan. Don't give up on it! Good shootin, Steve
