I don't believe I ever posted this here. I take part in the Nobelese Largesse artisan swap meets, coordinated on Facebook. This was the item I created for Konstantia Kaloethina, "Azure, a standing seraph argent, a bordure gyronny argent and sable."
I decided to try enamels, and didn't get it as even as I would have liked (though the subtle texture of the glass may have inhibited this as well). This was better a task for flashed glass, but the swap limits the expense of items that can be used. The border, black and white/silver, is clear and dark smokey-colored glass.
I'm particularly proud of the seraph, because I did it entirely by hand. I didn't trace anything or use a visual reference, I just pulled to mind a seraphim and started scrubbing it out.
