Idea for skins project - butterfly wings / cocoon

Mum just inspired me! I really love looking at the microscopic images of butterfly wings and how they are the skin on the wings so the butterfly can fly! She mentioned that they have a butterfly farm at her school and how they can watch the butterflies "shed their skins" and turn from caterpillars into butterflies! This have me a great idea to show the shedding of the cocoon and the bright butterfly underneath! I'll do some initial sketches later before the idea turns to mush in my brain - but this idea looks like a good one :D fingers crossed!
