I've been doing rawhide backong over hackberry bows lately.  The rawhide takes wood stain rather nicely, but the hackberry is not very porous and really doesn't like oil stains.  So, I have been sanding the little bit of stain off the hackberry leaving that pale soft butter yellow to stand out against the darkened rawhide.  I kinda like the look.  I'll try to get someone to take a digital photo to show you.
