You can add a special touch to your ceremony by lighting a Unity Candle. It can also be a lovely way to include members of both families so that they too can unite together as one family. Couples use two lit taper candles which symbolise their individuality, to light one big candle as a symbol of their two lives becoming one in commitment. The Unity Candle Ceremony is a meaningful, spiritual symbol of life, light and the eternal spirit of love and caring.
