One of my lovely coworkers, Michele, was wearing this lovely earring the other day. It would make a great applique pattern or quilting design. You could put a block in the large circular area, a flower or something. Or you could fill it with an interesting fill pattern.
You never know when you're going to find inspiration
Here I drew a rough drawing of Michele's earring and duplicated it using my trusty mirrors. This definitely has possibilities, but needs refinement!
