10. Creepy Crawly Wall Invasion
Give your guests the ultimate skin-crawling sensation with a 3D wall invasion of realistic black paper bats or spiders. Cut out dozens of silhouettes of bats or spiders in various sizes from heavy-duty matte black cardstock. Gently fold the wings of the bats or the legs of the spiders upward to give them a three-dimensional depth. Using wall-safe adhesive putty, arrange them in a dynamic, swarming pattern that starts from your fireplace, a window, or a corner, and climbs diagonally across your walls and ceiling. The shadows cast by the folded paper limbs and wings under your normal room lighting will make it look as though a massive swarm is actively invading your home.
