Oooh, have you picked out your flowers yet? Hydrangeas are gorgeous in your wedding colors!
With centerpieces, simple is more sophisticated and cost-effective. Tea light candles are cheap and make for a nice atmosphere. There are tons of different things you can do with the candles too. Do you have a theme? You could create one. For example, I'm doing a beach-themed wedding so I'm having a fish bowl in the middle of the table sitting on white sand, with tea lights and sea shells all around. The fish bowl will have turquoise rocks. Another idea I had but decided not to do is a sailboat tealight holder.
Isn't it cute? If you give me a theme to work with (or season) I can probably think of other cute ideas.
