Pretty backdrop for the wedding party table. Tulle and twinkle lights make beautiful wedding decor. Maybe do a solid white tulle with lights for the whole barn and this accent in red behind the head tables?
Candle table centerpiece (inspiration only) Glue fake flowers to the bottom of a tall vase (or to stones you could drop in), fill with water, and top with a floating candle. This is a really cute idea for center pieces!
