Cut wing shapes out of red posterboard and then cut small circles (try tracing a glass for the right size) from black posterboard, which you glue onto the wings.
Punch two holes at the top of each wing and thread some black twine or yarn through them, knotting them over your child's shoulders, backpack style.
Then use two black pipe cleaners to make antennae. Either twirl the ends or attach a black or red pom pom to the end.
Wrap the unadorned end of the pipe cleaner around a dime store headband and place on your child's head.
