Room boxes are a cost- and time-effective way to make miniature settings without attempting larger setups such as a dollhouse or train set. Commercially bought room boxes tend to be made of wood, pressed wood products or plywood, with the top and front window made of removable clear acrylic that lets in light and enables access and viewing from two perspectives. Dimensions usually meet standard dollhouse proportions ("1:12 scale" in dollhouse speak means that 1" in the dollhouse world represents 1' in the real world), but anyone can make a room box from a leftover shoebox, orange crate, etc. and adapt an idea to suit the box's scale. Since any material can be used, whether leftover or new, people of all economic classes express themselves through this craft.
