I think the addition of charms would be a terrific idea. I know that Joan Rivers has a line of egg charms for necklaces and bracelets, and although they are a little pricey, they are very nice. She sells through QVC, so you might check their website to research the idea. I would be very interested in the charms, especially if they were nickle free as I am allergic to that metal, and if you added crystals, I do not know if it would be more expensive or less, but my mind is racing with the sort of charms you could come up with for the Villagers.
