Handfasting is an ancient Celtic custom, historically common in ancient Ireland and Scotland, in which two people came together at the start of their marriage or relationship. The couples hands are gently tied together with ribbon. Following this, pieces of coloured ribbons, each representing positive aspects of a loving, long, marriage, are added to the couples handfasting. This practice gave way to the expression "tying the knot" which has come to mean getting married or engaged.
