has anyone replaced their ugly fake wood flat interior doors? I would have by now but... the partition (interior) walls are 3 inches in width and all standard interior door jambs at home improvement stores are 4 inches in width. So, the only options are buy them and try to cut them to 3 or, build our own jambs, and buy doors only. But Iam not sure how to recess the door hinges into the jamb. I do not want to keep the jambs as they are, like everything else that came with the place, NOT REAL WOOD but pressboard. Any ideas? Anyone else done this???
