Wedding Traditions in Ireland
Handfasting is an ancient Ireland Celtic tradition, in which a man and woman came together at the start of their marriage relationship. Each partner holds the hands of the other, right hand to right hand, left hand to left, their wrists crossed. The ribbon is wound around the wrists over the top of one and under and around the other, creating the infinity symbol. The practice gave way to the expression “tying the knot”.
Having empty chairs across from the bride and groom is a Scandinavian tradition. The signs aren't necessary, guest just know that they are invited to come and chat. This is a simple way to take the pressure off of the bride and groom to do a receiving line or make it around to every table to greet everyone. This way the newlyweds can actually sit and enjoy the meal and it's up to the guests to say hello.
