Steps:1. Draw a paper template of each side of the house, and then trace around each window and door to transfer the designs to the foam (figure A). Cut them out using a utility knife. Glue the four sides together and reinforce the corners by wrapping them with one-inch-wide strips of foam to give the foundation of the house some strength.
2. Cut the roof, door/window casings and trim, mullions and chimneys out of other colors of foam and glue each piece in place.
