We love the red and whit roses idea. Red Wedding Bouquets, Red bridal bouquets - these were the wedding colors I wanted but I was too busy doing what others wanted/approved of ("black is for funerals"). Maybe for our vow renewal
Use of blue lighting within a white wedding. Several different types of floral arrangements were used to accomplish this look: mixed smaller arrangements, tall glass cylinders with sprays of orchids, and opulent display pieces perched on top of pedestals
I have also seen similar centerpieces that use epsom salts instead of sugar. You could also sprinkle a mix of pearls/gems. Sand (or sugar), faux pearls, a 3 candle. An easy DIY wedding centerpiece idea.
