My fiance and I are planning to do the unity candle because it is a tradition. However, we also wanted to do something in addition to that. Sand is an option but I feel that it's almost become overdone. I have read about knots and don't like those ideas. Also, we don't drink so I don't like the wine box idea. I LOVE love love using two colors and painting on a canvas but his sister just got married recently and she did that so I don't want to copy. Suggestions???
