A flowers with candles centerpiece is always perfect, no matter what the occasion. When lit, the candles create such a lovely ambiance so this would be a great wedding centerpiece. Just choose the flowers you love, in colors that will go with your wedding colors. Choose the appropriate colored tapers.
Candlesticks can be different at each table or you can go somewhere and buy enough of the same kind. They have nice looking taper holders at dollar stores so you don't have to spend a lot of money.
The bowls at each table can be different as well, as long as they are color coordinated with your wedding decor.
