Has anyone heard of this? We got engaged on the beach (as per the pic), and our time spend in Northern Michigan growing up at our summer cottages is a huge part of who we are. We thought it would be really fitting to include a sand ceremony in place of the unity candle. We would combine sand from our respective beaches to symbolize the intertwining of our lives. Have you seen this before? Any ideas for glass containers to use? Places to buy them? Thanks!
