"Love this idea for collecting cards (that are also the gift). I always feel a little leery about leaving my card/gift just laying on a table." Allie, wouldn't this be good idea for wedding gift cards?
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.
