Sculpting Backwards

No, sculpting backwards isn't an option in Cranium...It's how I created these little relief sculptures.

Bird Party, 2008

I carved these little guys into clay, built a 1 inch foam core wall around each piece and poured in plaster. It was totally guesswork and luck but they came out looking reminicient of japanese woodblock prints or something like it...

Whats with all the party hats you ask?...
