I did cover the tables with plastic table cloth before hand, had lots of napkins on hand and I was able to get inexpensive spray bottles for tiny fingers by shopping in the travel section at Bed, Bath and Beyond. The kids loved the project and two grandmothers ended up asking me if they could make butterflies too which was great. The coffee filters didn't take long to dry although I admit to speeding up the process by hanging clothes pinning them to my desk handles so they would dry even faster. I had coloring sheets on hand for the kids to work on while they waited for their butterflies to dry.
Spray Bottle w/ water
Magnet Tape (optional)
1. Color your coffee filter with markers. Make crazy patterns but remember that everything is going to blur a little bit. (Note: If the markers you’re using are drying out the colors will not run as much later)
2. Lay the coffee filter on top of a plastic tablecloth or layer of paper towels and spray 2-3 spritzes of water on to the coffee filter. Allow coffee filter to dry. (You can leave it laying flat but it dried faster when I hung it to dry.)
3. (Version 1) Pinch the coffee filter in the middle and use a clothespin to keep it pinched. Fluff the wings if they look too scrunched. Wrap a pipe cleaner around the top of the clothespin leaving the ends free to bend into antennae. If you want to turn this one into a magnet you can put a strip of magnet tape on the back of the clothespin.
(Version 2) Pinch the coffee filter in the middle. Fold the pipe cleaner in half and stick the pinched coffee filter in the middle. Twist the top of the filter a few times leaving the ends free to bend into antennae.
