Creepy Cloth Runner
This may be the easiest (and cheapest) way to decorate for Halloween. Even banisters can get a dose of festive flair. Delicately drape this cloth over stairwells for a creepy vibe, or you can display it over a doorway to warn your party guests that the room is off limits. For a surprising décor trick, place them on a side, coffee, or console table along with your everyday accents. This will also work outside on a porch, draped over front yard bushes, or hanging from your fence to welcome your trick-or-treaters and give the outside of your house a mysterious edge.
