I'm not sure where I first read about/saw coffee filter butterflies but I know that I've done them with every group of children I have worked with since. Because the are simple, but allow for self creativity, they've been a hit with every age range from toddlers to grade schoolers. Truth be told, I enjoy making them myself and I'm thirty. Even though we haven't been crafting much this summer ( my boys prefer sand and mud to crayons and paint) I couldn't let our insect unit go by with out making them. Our Supplies: 2 coffee filters, a clothespin, a pipe cleaner, scissors, glue, & dot markers * if you don't have dot markers using diluted food coloring (dipping or with droppers) works too
