Below is a wedding from the Washington Duke Chapel and Marbles in Raleigh. I loved the green bridesmaids dresses that the bride chose they looked great with the ivories, pinks and peaches.
She chose simple but elegant centerpieces for the reception - 3 cylinders of varied heights w/ tropical leaves, floating candles and rose petals.
For the cocktail tables we used small cylinder vases with bear grass wrapped inside and a floating gerber. I also think flowers on cocktail tables are a nice touch and they don't have to be large just a detail to coordinate with the overall look.
