All kids networks has a great butterfly craft for kids to make and shares an example of ink blotting using a butterfly cutout. Kids will love to paint the one side and see how the wings become symmetrical. Their post includes a butterfly template printout so all you need to do is cut out the paper.
Piggy giggles has a really simple paper napkin butterfly project. All the kids need to do is color the napkin with markers, spray with water and tie up with a pipe cleaner.
No time for flash cards creates a butterfly sun catcher which uses construction paper, contact paper, ribbons and crayons.
