I'm going to try another rehab project. My under counter cabinets have no shelves so it's 34 inches of vertical space. Most of it is wasted with stuff piled on top of stuff so I always have to dig to find what I want. I'm thinking 1/2 depth shelves about 1/2 the height of the cabinet. I've got 2x2's , 1x4's and half of a 3/4 inch plywood sheet I want to do at least two of the cabinets leaving one full height for the stew pot.
