Treat both sides
Okay, so I should treat both sides the same, that's good advice. And I should also use some sort of sealer instead of polyurethane? Here are some photos as well. What do you mean when you say the shellac should be de-waxed?
When you say to use an oil stain instead of mineral oil, I'm not sure what you mean. I use the combination of mineral oil + cocoa powder to fill the voids. My understanding is the thinned shellac blocks that cocoa mixture from entering the wood. I could also use some sort of wood filler to accent the carving instead of the cocoa stuff, I would think and then use a putty knife to scrape off the excess. You can see it is still a bit warped (though not as much as it was since I treated the back side with mineral oil). The side view has the carving on the top, with the back towards the bottom. The carving itself takes very little actual wood out of the piece.
