Just because her 30th birthday is at a bar doesn't mean DearSugar can't decorate. She'll head to Le Colonial hours before the party begins to set up a fabulous look. When done correctly, balloons, metallic streamers, and confetti can be fun. Cotton napkins make the event more sophisticated. Have the wait staff serve the appetizers on silver platters. Fill vases with lilies, the birthday girl's favorite flowers, and bowls with sour gummy bears, the birthday girl's favorite candy. Light hundreds of votive candles and use pretty rhinestones as shiny accents.
