Colleen, Tery and I experimented. Colleen made the most incredible crown. I can see lots of these in the future! I made a few more examples to resemble opals and blue mother of pearl. I made a bezel of seed beads around one, added a fringe of swarski crystals and a pinback. Haven't decided what the green resembles yet, but it is very pretty.May propose this as a class for an upcoming seminar. Would love to know what you think!
