I have a large window I need to cover with plywood.
My brain says it can't be done without putting a strip before the
sheet and just make 3 equal pieces. Maybe someone can suggest
something easier. (It would be nice if I could get a piece of plywood
58.5 X 51.
The window is 58.5" high. The two side windows are 28" wide and the
large window is 51" wide.
