Last year I did my door as a mummy. I wrapped the door in white crepe paper. The problem was overnight the cool air got between the door and the storm door and the mummy's wrapping drooped. I was so upset I almost tore the mummy down. My daughter and my husband liked it though so I kept it up. If you want to do a mummy door I would do this on an inside door, like a garage door or bedroom door or the back of the front door.
Since Frankenstein is green and my door is red I decided to do just an angry face.
To do this door you will need a large yard trash bag, 2 paper plates, a cup, tape (I used packing tape) and 2 pieces of black construction paper.
