Luvglitz, once you start making tin cups it really opens up an entirely new world. I love layering my necklaces, so my tin cups and strands usually come from single lots. Make sure you wear a strand of Tahitians to the show, that way you can match quality. I know battah was able to purchase some lovely Tahitians at a recent show, but you might also want to look at some of the vendors here. I think someone mentioned buying a small lot of pearls from Jeremy.
