I was struck with inspiration this afternoon. You see, I've been struggling with how to make the radish earrings required for any good Luna Lovegood costume. I could've sculpted them out of clay, but that's not exactly one of my strong suits, my search for charms that look like radishes had been fruitless, and any handmade earrings for sale on Ebay were running upwards of $20. I'm already going to have to spend a pretty penny on a skirt and tie, so 20-30 dollars on a pair of earrings I'm going to wear once a year isn't really an option.
Then, while in Joann's, I stumbled upon a set of spherical red buttons, and thought to myself that they could easily pass for a radish. I found some leaf shaped beads (in the process, I also found better red beads for my purposes), and it was as simple as that:

All you really need is two big red beads (1/2"-3/4"), four leaf beads (I used two each of different sizes), two eyepins (you could totally use headpins if you wanted, I had eyepins on hand, and I think it makes the bottom look more like the squiggly radish tail), and french hooks or whatever post you prefer. Put the red bead on the pin, followed by the leaves, make eyes, and attach to the hook.
I'm really pleased with these. Now I just need to get hooks, and then work on the Butterbeer necklace - I picked up corks for that today. They're soaking, and should be ready for stringing up later this week.
Huzzah!
