I just submitted and necklace for entry in the Art Bead Scene October Challenge - http://artbeadscene.blogspot.com/. The theme this month is "A Dark & Stormy Night". My inspiration was these unique carved agate rondelles that are navy, dark gray and white. They reminded me of the colors in storm clouds. You can go to my Flickr page to see more views of the piece or you can check out the Art Bead Scene Flickr group - http://flickr.com/groups/artbeadscene/ and website for more info.
