Against the advice of my mother and my day-of wedding coordinator (a worthwhile splurge, but that's a different story for a different day), the one thing I just didn't care about for my wedding day were the flowers. I wanted a beautiful wedding, sure. But I knew that you could have a really gorgeous event without even a flower in sight.
Putting a taper candle in a bottle is a dramatic centerpiece detail at weddings and events. Decorate the bottle with paper, twine, flowers or sprigs for a personalized look. http://www.lightsforalloccasions.com/c-63-taper-stick-candles.aspx
