I don't make earrings that often. I usually wear ear cuffs instead, so I tend to forget that there are other types of ear jewelry. So I kind of surprised myself when I actually wanted to make a pair of earrings one day.
I actually made the copper and coral first (the last photo). I liked them so much I decided to keep them. Then I made the copper, silver and blue earrings, which gave me the idea to make them with just mixed metals and no beads. I think I like the one without beads best.
And, yes, there is a tutorial on the way for the mixed metal version. I've already edited the photos for it. I just need to find time to put together the final document.
