Somethin I just read here in another post got me thinking. I was up in Wisc a couple years ago and got me a pile of birch bark and brought it home. About half of it is still settin up in my attic waitin on me. I was wonderin if there's anyway to use it as a backing-- just for looks, as I know there wouldn't be any tension advantage with it. Can it be soaked and made pliable again? Or is there another way to make it workable?
