I built a 72"high x 36" wide cabinet for an armoire, using solid core maple plywood for the sides of the case. My intent was (and still is) to install 2 flush doors so that the armoire can be closed. I plan to use three hinges on each door. But the sides of the cabinet have bowed slightly -- the widest part of the bow is about 1/2" wider than the top and bottom. So each side is off by about 1/4". The bowing is not perfectly symmetric -- it's more pear-shaped.

I can (with some effort) make doors that have a matching bow on their outside edge, but should I attach hinges in the normal way with the normal distances from the edge of the side and the edge of the door? Or would It be best to mount the middle hinge in a 1/4" spacer? Would that mess up the way the edge of the door closes, and if so, is there a solution to this problem?
