Shadows are emblematic of Halloween: They're dark and fleeting, and always lurking a step behind you. But decorating with them is impossible -- at least without black magic. Use some black paper and a little craftiness to make silhouettes, and you'll get the next best thing.
Spine-chilling as it sounds, a colony of bats hanging from the highest reaches of your house serve as the perfect welcome for guests -- if you're throwing a Halloween party. You can also clip these clothespin bats onto tree branches or bushes outdoors to greet trick-or-treaters.
Cobwebs, incorporated into the fireplace's molding, provide a resting spot for long-legged critters.
To make them, print out our cobweb labels on self-adhesive computer paper. Affix to the molding of the fireplace or any other place in the household where spiders might lurk.
