Here are the latest pieces for sale up on eBay. The link to this auction is: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7397519225. The wings and wand are painted in interference paints, somewhat like iridescents but they change color depending on how the light strikes them. I also use salt to make that interesting texture in the background.
The other here is a longhaired Dachshund angel, whose wings are also painted in iridescents. the link for this auction is http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7397497207
