I tried to make a headliner using a piece of highly bendable plywood I got at a cabinet shop but just could not get it to fit right so went this route. The front and back are identical to what you would have if you did use a full headliner. I made them in 2 pieces using the multi piece paper template method. The pieces down the sides finish it off. Used white duct tape to cover the seams. First painted the already textured ceiling with two coats of Rustoleum semi gloss white.
