I wanted a bench by the back door... ADDED NEW PICS
..so I made one.
Before (an old shelf we had in the basement)
cost - $4 for the plywood for the seat, everything else was leftovers from other projects
I wanted to keep a middle shelf more for stability (keep it from twisting) than for function. I did decide though, once I had it in the house, to invert the middle shelf to gain a little more space above it, now it fits our slippers perfectly. Turns out that finishing both sides was a good idea...
