Such a simple and yet wonderful idea! I turned this into a project with my three year old: watercolour brushes on (good quality) children's drawing paper, scissors, my kid's glue stick et voilà X-Mas gifts for family and friends. Thank you, Joly!

First batch of butterflies arranged on my sketchbook. :)

And yes, I'll definitley try and use _my_ watercolour practice sheets or even "artwork" for butterflies.
