Burlap, which is composed of jute fibers and which may be found in garden stores, makes a great backing. Simply cut it to size and glue it on with a wood glue. Two pieces may be oined at the handle. Once the glue dries, trim the edges with a scissors or sharp knife, and sand as needed. Reapply glue to any frayed edges. The burlap may be stopped a few inches from the nocks.
The burlap may be stained and finsihed with a urethane sealer.
As it happens this board stave developed a crack at a nock end.
To prevent the crack from creating a problem I glued on a mahogny overlay.
I shaped the nock and overlay.
Here is the bow at ful draw.
