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.
Only a handful of the many weddings I work every year do I get to stay until after the ceremony for touch-ups and a hair change. Today is one of those weddings and I couldn't have asked for a better bridal party to hang out with!
