Has anyone tried doing floating sprigs of hydrangea in tall vases filled with water for centerpieces? I'm thinking of having 3 vases (tall, medium and short) filled with water on each table. The tall and short ones would have sprigs of purple hydrangea on top, while the middle one would have a floating candle and possibly be filled with sliced limes. I haven't tested it out yet, but I'm wondering if anyone can provide tips before I try it. Thanks!!
