I did take the suggestions to heart and made a little something with Akira Yoshizawa's very famous butterfly. The Yoshizawa Butterfly is, I think, one of the most beautiful yet simple butterflies that I have tried. It starts with a waterbomb base and is very quickly turned into a butterfly!
What I did with the butterfly, was to make a whole bunch of them in rainbow colours (or at least most of the rainbow colours) and place them randomly to a while background to form a collage of sorts.
If you notice closely, you will see that the butterfly wings are not completely flattened and the butterfly itself does not lie flat. This was a small variation I picked up from Nick Robinson's blog, where the wings are folded but not creased and a mountain fold holds the butterfly shape well.
