DIY Halloween decor ideas :: Use a white stocking with stuffing inside and add more spiders to the bottom then around. You could also put a glow stick in a water balloon and have it look like they're surrounding a glowing egg sack.
Ghosts for a Front Entry - plastic bowls with drilled holes in the bottom, turned up-side-down and threaded to the ceiling secured with duck tape; and use cheese cloth or white fabric with felt faces secured to them :D
Halloween Lanterns - punch a small hole in bottom of some paper cups. Glue a pair of googly eyes onto side of each mini paper cup, about halfway between top & bottom. Hang string of lights. Push 1 or 2 lights through hole in each cup (",)
