I believe that most woodworkers are very in-tune with where their wood comes from and all of them that I know of, will go to great lengths to use their lumber sparingly to make sure there is a little waste as possible. Many, like me, will also take advantage of obtaining used lumber, also called salvage or re-claimed lumber. There is often a bit more work in using this wood but there is also a bit of satisfaction knowing that it wasn't just simply sent to the landfill or burned, and that it could be re-used for other things. I don't go out of my way looking for this wood, but I never pass up an opportunity when I see it.
In this case I was lucky to get quite a few sheets of 1/8 plywood paneling that had been removed from the interior of a house. I have been using it for cabinet back and jisgs for many many years. When I decided to make this finishing products storage cabinet I immediately though of using my re-claimed lumber stash.

Because I was using 1/8" plywood for the structure, in order to make the cabinet sturdy, I ended up using 2" x 3/4" as the shell to glue the plywood to. This made a very strong but surprisingly light cabinet. Much lighter that say using 3/4" plywood or a similar structural component, and for something that is only holding storage items, this was more than adequate.
I was fortunate to even find used hardware for this project, even the wheels, door pulls and hinges were re-claimed from some other project somewhere and I purchased them from the the Habitat for Humanity Store that I frequently visit and am happy to help contribute to ... they do good work.
Of course the main purpose of this cabinet for me, is to get all my wood finishing products in one location. I have, on occasion, made trips to the hardware store to purchase product, like varnish, to finish one of my projects, then after I have opened and used it and put it away, I discover I already had a can of this in a place I had forgot to look, so hopefully this cabinet will help me be a bit more diligent in using what I have first .... hopefully.
