Open for business! Forget storefronts fashioned from pillows and blankets: This cardboard grocery will be little ones' new headquarters for imaginative, enchanted play. 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 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.
