God’s creation in the ocean is magnificent. As an avid scuba-diver, I have the privilege to enjoy this majestic world on a regular basis. As creative people, we basically recreate what already is, from the perspective of our mind’s eye.
Some very clever people have shared techniques to recreate these effects with polymer clay. For wonderful instructions on making an Abalone cane see http://www.polymerclaycentral.com/faux_abalone.html and for Paua shell see http://www.polymerclaycentral.com/faux_paua.html
I still have some of these canes left-over and am excited to try different things with them. Enjoy as you create!
