Over time I have accumulated a number of MinWax 8oz. cans of stain.   One of my large bins is dedicated to paint and has held these stain cans.   After pulling them all out on the floor for the umpteenth time, I decided I needed to get them organized.   "This sound like a job for SuperMan" (maybe super plywood mitered shelf)!   I always have a few pieces of 3/16" plywood underlayment (from Lowes) laying around so I sprang into action.   Mitered plywood makes very good cabinets, shelves, storage bins, etc.
