Thanks everyone!
Traxx, I thought using juniper bark one day after looking at some tissue paper backed bows. It occurred to me juniper bark was very similar to it when it was thin.
In case anyone is curious about the process i used. I seperated the bark into long thin strips and glued them on the back. The only problem is juniper bark has a lot of different layers and they kept peeling back up. So I sanded the layers down to a consistent thickness and spread a layer of tb3 thinned with water over it and let it soak in. After that it made a few crackling noises but stopped after a few shots.
