Using black paper or fabric, bats can be traced and cut out to decorate your front door. They can be put on the front door via tape or any other method that you like. A bat template can be found for free on a lot of different websites. Spiders can be created with Styrofoam balls. These are spray painted black. Black pipe cleaners are used as legs, and voila! These Halloween door decorations have a life of their own, and boy do they look the part. For something a little more cartoony, a different color can be used – which also creates an intense look depending on the colors used.
