The Pre-K class is studying bugs and butterflies. We made butterflies using shrink film and Crayola Gel markers. I baked them in the oven at 325 for 3 minutes. They got a little bendy- it looks like the butterflies are flying. Next time I might sandwich the pieces between two sheets if parchment paper. The preschoolers loved using these new materials and they will be so excited to see their finished, shrunken butterflies!
