mixing of the sands box
This is the alternative to the unity candle at weddings. It’s called a mixing of the sands. The bride and groom each have a different colored sand and they each pour the sand in the box. As the sand mixes one it symbolic meaning is becoming one. Two it creates a cool design that is a wedding keepsake. This is mine from our wedding last year.
