Take several clothes pins and put them on newspaper. Paint them to look like the bodies of what will be butterflies. Take 1 colored pipe cleaner and cut it into 4 inch pieces. Use 2 of these and curl the ends to look like antennas. Place the remaining straight end into the mouth of the clothes pin and glue to one side on the inside or out. Glue eyes to the top of the clothespin. Fill the ziplock bag about 3/4 full of their favorite colorful snack.
