I don't know if this is true for all brides, but for many of my brides deciding what to do for the unity ceremony can be a tricky decision. Especially for outdoor weddings, most of them do not want to go the traditional unity candle route. When Emily stumbled across the old tradition of a salt covenant, I was incredibly excited both for her finding a solution to her problem and to now be able to share this idea with other brides!
During ancient times people would seal covenants and promises using a salt covenant. Taking their individual salt pouches, each person would take a pinch of their salt and drop it into the bag of the other person. The agreement could not be broken unless an individual could retrieve all of their own grains of salt from the other's pouch. There is also added meaning because salt is generally associated with adding flavor and melting ice, two things which are very good for marriage (I'm sure you can draw your own analogies.)
You can easily buy many different colors of salt on Etsy, if you like, or stick to traditional sea salt if you want to preserve the full symbolism of the covenant. I really love that this is not just a ceremony with deep meaning, but also with many customizeable options to suit each couple.
Will you be doing, or have you seen anyone do a salt covenant at their wedding?
