Gerber daisy wedding bouquets are very popular for all types of weddings. Here are some ideas and photos along with other ideas for bridal bouquet design.
I like this centerpiece idea! You could have each level be slightly different--pearls/rhinestones, flowers, candles, etc. DIY Wedding Centerpieces like this one are perfect for an outdoor wedding.
