I've been asked to design a rolling set piece that contains a 4' half-sphere, part of a fairy throne (imagine a hollow ball, sliced in half vertically, with the front face removed). The "shell" needs to be fairly thin, say 1-2 inches, and it rests on a wagon. I'm stumped figuring out the best materials to use. This is a low budget ballet production, so I can't go crazy. My favorite idea so far is fiberglass, if I can figure out what to use as a mold (hard to find 4' EPS spheres!). Or maybe a foam block, carved out and surfaced with AquaResin or plaster, but that's a lot of foam to carve.
Other ideas: EVA foam cut into strips and glued seems too flimsy. Chicken wire and papier (or cloth) mache could work, but what to use to stiffen the opening?
Thanks for any suggestions...
