I've used these mostly in earrings, and they always look great.
Start with simplicity, keep it simple...
These are a very basic elements for just about any piece of jewelry. In that they are simple, I decided to use them in a very simple earring design, which turns out to be a great seller of mine. I simply dangled one of these hammered sterling silver domes off the ring of a ball post earring and voila - instant earrings. Cute, simple, and boy do they sell.
Great little hammered charm, or even one of the larger ones, make a great addition to a simple charm bracelet. Hammered metal is in right now and the piece lends itself to dangling teardrops over its front. Very cute and useful.
I attached them to long chain and the finished item looked very expensive. I love it! Perfect charms for summer jewelry.
