Tickets ready? Forget forts fashioned from pillows and blankets: this cardboard theater will be a little one's new headquarters for imaginative play where they're always cast as the lead. It even doubles as an art project, with a ready-to-decorate interior and exterior that let kids create a custom look. Just add markers—or paints, wallpaper, glittery glue and anything else they can find in the craft drawer! Best of all, it's formed from one single piece of cardboard, so assembly is as easy as folding the pre-scored sides.
