This was a pretty easy project. We could use more shelving for storage of bath towels, dish towels, wash cloths, etc. We didn't have much need for hanging space that was in the wardrobe. So I made a shelf out of some lightweight 1/2" plywood. I installed four small corner blocks and screwed and glued them into the existing wardrobe corners. I then used construction adhesive to secure the shelf to the blocks. For cosmetic purposes, I glued a 1/4" strip of oak over the exposed plywood edge. My wife liked the shelf so much, she asked for another, only a bit higher. Unfortunately I didn't have any more 1/2" plywood, but I had a bunch of 1/4" plywood. So I tried it, just to see how it would work. I installed the shelf the same way. It's OK for light things. When I get more of the thicker plywood, I might do it over again (probably not).
