I've been playing with the sun and moon theme recently. At first it was the crescent moon shape, which actally turned out to be much more difficult than I thought it would. I tried using different pens, markers, nail polishes, anything round as a mandril to get the curves just right. Finally I ended up shaping everything completely by hand in a very, very long process.
To make the sun, I thought the gold wire I had sitting around would be perfect. As well as the beautiful yellow citrine briolettes that I don't use very often.
And the combination of the two
This one was difficult because I used a thicker gauge of wire. The whole thing, except for the wrapping was made with just one piece of wire.
