Here's the enamel pin I mentioned yesterday. I used a stamp for the basic shape-- I reversed the stamp by using it on a piece of polymer clay and using that as the stamp to imprint the silver clay. The silver clay was then fired, then I used the wet-packing method to add enamel, then fired again.
I should have taken a picture of the back, as well. I'd originally made it using a finding set that had separate sockets to be fired in place and a pinback part to add after firing was complete, but I lost the pinback and had to make a new one. I used heavy-gauge silver wire, hammered on the ends to give me a thin flat surface, which I drilled with a Dremel tool. Then I used eyeglass screws to fasten the pin back parts to the pin.
I kind of wish I'd used the other shade of blue, rather than the dark Prussian blue, to contrast better with the Concord purple and transition better to the Peacock Green, but my mom was happy with the result.
