Assemble four 2-by-4 pieces of wood in a square shape on a horizontal surface. Hammer nails to attach the pieces of wood together until the square is secure. This will be the frame for the puppet theater.
Stand the frame up vertically. Lay the remaining 2-by-4 pieces of wood horizontally flush with the outside edges of the frame. They will be parallel supports to keep the frame standing upright.
Hammer two to four nails through the frame and into each support until secure.
Stretch your linen sheet tightly over the wooden frame and secure with hammer and nails.
Position your light source, the lamp, behind the white screen. The light will shine toward the audience from behind, with the puppets being manipulated between the light source and the back of the white screen.
