I have been saving mica chips I got out of my driveway from gravel delivered. But for those interested, I think you can by bigger chips at Michael's craft store in the rubber stamping sections. I used my new love... low-e glass. I discovered that depending on which side you fire against the chips, you can get a beautiful, golden, bronze-like halo around the mica chips.
This piece is a 5x5 sushi like dish and has clear rubber bumper feet. It would make a gorgous candle base also! I will put it on my Etsy site for $25 plus $5 shipping by Priority Mail. If a person where to order from my blog, I will sell it for $22.50.
