I'm using a tall, thin oval vase. I have clear beads/crystals on the bottom and then I've been pushing orchid strings down in to the beads to hold them in place. Once the orchids are positioned I added a floating candle to the top. We've been trying to figure out how to make this as easy and quick a set up as possible come the morning of the wedding. My mom suggested getting little blocks of foam to put at the bottom of the vase so we could position the orchids a head of time and then just put them in the vase, but unfortunately the styrofoam with the flower stems floats to the top when water is added. Has anyone had this happen or have any idea what I could use to weigh down the styrofoam so it stays on the bottom of the vase? We are open to all suggestions! Thanks for your help!
