Yes the peace earrings were worn a lot. I had to laugh when I saw a pic of my daughter on face book, in a peace sign shirt. I should have saved my old clothes. Good idea about doing Mom's jewelry in a mosaic. I have jewelry boxes full of Mom's, that I haven't even looked at yet... alot of old costume jewelry.
Another idea is to use them in abstract panels or as the centers for small suncatchers...
