A sand ceremony is a very visible way of symbolising your togetherness. Your individual sands blend to become one, symbolically blending your lives.
If you are having a beach wedding simply scoop up the sand beside you, perhaps using sea shells to pour the sand into your glass container. You could add the shells to the sand, then when you have your beautifully framed wedding photo you can display them together in your home.
There are many different coloured sands you can use. If you have children, they can add their sand to yours during the ceremony bringing you all together as a family.
