Foamcore base. Plaster Bandages cover all foamcore. When dry, 2 coats of plaster of paris were brushhes on. Sponge painting with latex paint gave the illusion of marble walls. The collums were created using poster shipping tubes (Staples) and also sponge painted. Hi Gloss medium was applied over dried paint. For the floor pattern, I sponge painted large areas the proper color schemes and then cut them into their shapes with a sharp exacto knife. then glued the pieces one on top of each other. Hi gloss medium protects the floor.
