White Roses and Baby's Breath Centerpieces in Martini Glasses ~ Your choice of color of Roses - consider gold accents. The Martini Glasses have a lovely shape. You could alternate the flower colors or glass colors Wonderfully simple idea
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.
Buy rectangular vases, fake flowers, rocks, ribbon, and candles the width of the rectangle. Glue the flowers to the rocks and fill with water. Float the candle up top. Glue the ribbon around the top of the vase.
