Polymer Clay Chameleon:
These cleverly-constructed interchangable polymer clay rings caught my attention at Flickr this week. The author is Bettina Welker (http://www.beadworx.de/), a German polymer clay artist, whose works I've seen and admired before. Her jewelry usually has a certain modern flare, great colors, and clean lines. Bettina recently published her first book, which is available in German (with project translation in English, French, and Spanish).
