Lucy from Crafterberry Bush made this entomology butterfly plaque out of air dry clay. It is so unbelievably gorgeous and it simply cost her $2.50 for the pack of clay.
Her original inspiration came from Ballard Designs set of 3 Entomology Plaques.
You have to go to her blog Crafterberry Bush and see just how close it resembles the real deal. I am amazed.
