I am making my own centerpieces for the reception and need some advice. They are going to be very simply 10inch lily bowls with floating candles and gerber daisy's in them. I want to put some vase gem rocks in the bottom and found some online that I love. The problem is that I have NO idea how much to order! They come in 3/4 pound bags and I will have 15 tables. I know this is an odd question but I thought I would try. TIA!
