The blue one on the right took me a long time to do. I'd done something similar in gold wire and goldstone (yes, like the one on the right) with two sections when I was taking wire jewelry class. Coincidentally, Julian had picked me out a big Chinese bead with a dragon on it that I couldn't figure out what to do with, and the Chinese beads were kinda pricey to get when you're buying them all separately. So I eventually figured, why not do a wire thing? The bead's upright at Jess's suggestion, but the "add the tiny seed beads onto the wire" thing was my own weird idea.
I finished the earrings ages ago, but hadn't gotten around to connecting all of the wire pieces for months. But we were playing D&D today and I was doing jewelry (and later, the aforementioned iPod holder) during that, so I had the table space, daylight, and time. I probably would have made it a bit longer than a choker, or at least added extra space, but I ran out of chain.
As for the gold one, that was kind of an experiment too. I'd found two goldstone heart pendants that I wanted to do a lot with, and I had a lot of little goldstone balls left over from the wire jewelry class. I wanted to incorporate gold chain into it, and ended up just plain attaching all the beads I wanted to put into it into the chain. Saved me the trouble of finding "background beads" enough to fill out the piece. It's very autumny.
