A giant cardboard triangle painted golden-brown, with red felt pepperoni on top. The toppings are what make people shout 'pizza!' from across the room. It takes about 45 minutes, and it's a medium build: one big cardboard box, yellow and orange paint, and red felt. Cut the triangle about three feet tall so it reads from a distance.

Let it dry 1 hour.
Arrange the pepperoni on the triangle dry first.
