Place the doilies on a towel that you are not concerned about staining. Paint both sides of each doily with water. Be sure to handle them carefully as they are delicate and can tear easily.
Drip food coloring onto the wet doilies and spread it around with a paintbrush dipped in water.
Turn the doilies over so that the towel will soak up the excess moisture. Let the doilies dry completely.
Fold doilies in half and then in half again. use scissors to cut a simple butterfly shape by cutting a small triangle section out of the center of the doily's side.
Fold a pipe cleaner in half. Run the pipe cleaner up the center of the doily and twist at the "head" of the butterfly to create the antennae. Trim ends.
