15. The Mummy’s Tomb Wrap
Transform your window into an ancient, cursed tomb. Crisscross wide strips of tea-stained cheesecloth or white crepe paper streamers across the entire glass surface, mimicking the bandages of a mummy. Leave a small, horizontal gap near the upper middle portion of the window. In this gap, place a pair of glowing, battery-operated red or yellow LED eyes staring out into the night. This design is highly graphic, budget-friendly, and offers an excellent balance of classic monster fun and spooky mystery.
