I have built several of these Jelly Cupboards since the plans came out. Everyone really likes them, and they are super fast and easy to build. The last one had glass doors that turned out pretty well. I like to use plywood beadboard on the back to give it a little more character. I also like to use 'hardware cloth' for the mesh type doors (found at farm stores). It usually has openings about 1/8" or less but not as tight as screen, which looks perfect.
