Have some fun with decorating inside the house. You can split your room into parts (or decorate two different rooms.) One side can represent the “Light” side and the other one – the “Dark” side. The Light side can be decorated in light colors and with blowups of characters like Luke Skywalker, Obi Wan, etc. The Dark side can have dark sheets over windows, black poster board on the wall, pictures of Darth Vader and other evil forces.
