With green Pacific(Oregon) Crabapple I take the bark off and seal the back and end grain with shellac.I clamp it to a 2x4 and try and take any bend out so it, hopefully, will dry straight. All the crab I've gotten around here is kind of ropey looking under the bark. It's a really cool texture but be careful when debarking or it's easy to scrape(mark) the back.
