I made several of these. I am hoping to use them in rings and statement necklaces. There really isn't a process to making them, you can pretty much see how by looking at them, but even so, I'll describe it.
First, cut a long-ish length of wire. Bend it over twice, so that there are two bends that trail excess. One of the excesses should be a lot longer than the other. This one should be wrapped around the place where the two bends overlap. Wrap tightly, so that they get pulled together, and the bends become the two loops of the bow.
