No house would be truly haunted without a swarm of bats flying about. These cardboard creatures look terrifically lifelike dangling from the ceiling and walls.
For each bat, cut out two triangular ears from one end of a toilet tissue tube. Next, flatten the other end and staple it shut about 1 inch from the bottom. Cut a crescent shape in the stapled end to form the bat's tail.
Paint the tube black and let it dry.
Next, cut out a wing shape from a 1-foot-long strip of black poster board. (For a more hair-raising look, first glue a veneer of black felt to the poster board.) Staple the wings to the bat's body.
Glue on googly eyes.
Finally, staple the elastic cord to the bat's back at the balance point, then hang the creature from the ceiling.
