I was thinking fiberglass for its strength, but that stuff doesn't come cheap. I want to build a 4' tall, by 4' wide, by 12' long basic box. Will the canvas/glue combo really harden? I'm thinking the 12 oz drop cloth. With glue and canvas, is 2 inch foam strong enough by itself or does it call for other reinforcements?
