+1 to what kevin said. There are some neat pattern & colors to some linen if that's your thing. The rendezvous have some good linen choices. What makes you think it needs a backing? Do you know what wood the bow is? most here use Tru-oil gun finish. I use a little of everthing, try'em all is my motto. tung, teak and BLO, several stains, and shellac, lacq, and poly all work.
