In sets of three, no two sets are alike. We'd like them indoors, yes, but also outdoors on a garden table where we'd leave them and let the elements carve their magic further. They'd also be great for holding candles or cutlery for an buffet. And, since the stone toughens up a floral display, they'd also work in a masculine setting, where the suggestion of adding a few posies can be a skittish proposition.
