An open and close stage that's durable and delightful, made with only an old shipping carton, some paints/crayons and your imagination.

The flaps provide the doors ( curtains ) of the stage. An opening is cut in back or in the bottom of the box for the puppeteers.

The shorter flaps (if any) can become a peaked roof  above and a red/carpet below, or even the seats for an imaginary audience.

Decorate by hand with paints and crayons or copy an d paste scenes from children's books, magazines or Bible Tails stories to make your backdrop/scenery). And let children decorate the outside as desired.
