The shadowbox consists of three rooms 5" deep x 8" wide plus a small room under the roof. The ceilings are really low, but let's pretend it's an old, old apartment building.
The right wall of the shadowbox was badly warped when I got it. I sort of forced it into place, but the aftermath is crooked trim and windows that slant at an angle. I decided to line the windows up (more or less) with the trim on the bottom of the rooms. The weird angles at the top of the windows should be able to be hidden by the curtains. I hope.
Eventually, I'll be putting a brick exterior on the outside and some trim on the edges.
