I just go back from spending some time on different beaches in Greece.   What was so amazing about this trip, was I collected some shell fossils and beach pebbles with the most amazing colors - lime greens, purples, gorgeous blues.  I've been collecting rocks for years  but haven't seen such colors  in beach pebbles before.  So I'm making them into jewelry,  I think they will look great.  Still haven't managed to put on half my other modern collection, but at 38 degrees its been way too hot to work.
