To make a shoebox diorama, apply paper to the inside of the shoebox as a background, and fill the foreground with story elements to recreate a scene. Some different ways to set the foreground include applying paper cut-outs and different materials, such as cotton balls, for different effects.
Construction paper can set the tone for the background. Blue is a popular color used to depict a sky, and different shades of brown and white can represent mountains or clouds. To create an underwater scene with the diorama, stretch a piece of saran wrap in front of the shoebox to create a watery effect.
