We are having an outdoor ceremony and reception. Our colors are black and white with accents of apple green. We are going to have black tablecloths, white napkins, and apple green table runners. I want centerpieces that don't include flowers...our venue has a ton of greenery and flowers so I don't want a bunch of flowers that are going to clash with the natural beauty of the site. I was thinking of doing three vases of different heights with rocks and floating candles, and maybe a flower floating in the water. I was wondering if you ladies have any other ideas???
