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!
Will have tall vases filled with water as centerpieces- will either have floating candles if venue allows it, or LED lights. TBD if will have flowers in shorter vase as in this picture, or stem of some other flower in the water in tall vases.
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.
