Foamcore base including wall beams. Plaster Bandages cover all foamcore. When dry, 2 coats of plaster of paris were brushhes on. Watered down latex paint is then applied and absorbed by the plater giving a old weathered look. Sawdust is then glue on to the floor to create the illusion of sand. A plastic fruit basket bottom (dollar store) was glued to the ceiling to create the gas storage tank. It also was covered in plaster and painted to match the walls. Old speaker wire was cut at various lengths to make the pipes and old tan shirt was cut into strips and hot glue gunned to the ceiling creating an upside down awning look.
