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.
As fall is the most popular wedding season, your big day with beautiful nature and best temperature weather will be remembered forever, and not just in pictures and videos. Many of your guests will hold onto fond memories of your big day!
