I can't speak from extensive personal experience but having seen the stuff that he created I can say the flatness of his work area never seemed to bother him much or the final outcome. He made everything from huge custom kitchens to all hardwood boutique furniture and even fully functioning looms for Shaker Village. I used to have a ton of photos but they were lost with my old phone. This is the only one I've currently got. Obviously you can't tell the quality immediately from a photo but you can at least get an idea.
