This is off the top of my head but how about using 12x18" paper and folding
the left and right sides in to the center (9" point). These 2 flaps become
the doors and open up to reveal.....?.......perhaps something that tells about
themselves or the doors could be decorated to show how they appear to the
world (not physically) and when the doors are opened they can draw their true
selves inside. (kind of along the lines of masks that we wear ...our public
face and our personal face). try using different kinds of paper too..bristol
board for ex. The doors can also be decorated w/ various textural materials.
