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.
One more shot from this gorgeous tented wedding! Love, love, love the twinkle lights and the draped tenting. Tent outdoor ceremony string patio lights chandelier pink draping up lighting Austin Texas wedding country glam chic classic
Chandeliers and Outdoor Weddings - could TOTALLY hang a chandelier from the big tree. Could then install the chandelier in your house. Craigslist has them for cheap all of the time. Could even use just a candle chandelier and it would still look gorgeous.
