Here is a template of a butterfly. Ask a grown up to help you fold it down the middle. You can use a brush or your fingers to make a pattern with paint on one side of the butterfly. Fold it over, pressing down firmly and when you open it up your butterfly will have symmetrical patterns on each side.
