1. First, use the utility knife (adults only) to cut out windowpanes and a door.

	Materials
	• Four 40-by-60-inch sheets of 3/8-inch Fome-Cor (available at art supply stores) • Utility knife • Tempera paints • Paint roller or paintbrushes • Twine

2. Next, cover both sides of the walls with a base coat of paint. Add trim and wall decorations.

3. Now it's time to raise the walls. Cut three holes in each side (one in each corner and one in the center), 1 inch in from the edge. Thread twine through the holes and tie the walls together at the openings.

4. To hang curtains, cut holes through the walls above each window, thread pieces of twine through, and tie a curtain rod or dowel in place. Use the same method to attach a shoe box for a window planter or a cardboard canister for a mailbox.
