This tradition is usually associated with Hispanic and Filipino families. Lasso (sometimes called, "lazo") or rope is placed around the bride and groom's shoulders (groom's shoulder's first) in the form of an "8" (the infinity symbol) - after they have exchanged their vows - to symbolize their everlasting union. This is usually done by the officiant, however, family members can also take part in this ritual. The couple wears the lasso throughout the remainder of the service. It is sometimes made of rosary beads, white ribbon, orange flowers, fabric, silver, crystal or elaborately painted wood. It can also be placed around the couple's necks, or wrists. If you have children; they may also be included as they will definitely be a part of the new family. The Veil and the Lasso are both associated with a wedding prayer during the ceremony. Special additional members of the wedding party may be in charge of "lassoing" the Bride and Groom together after they kneel for the wedding prayer. They drape what is usually a white satin circle of cord around the shoulders of the kneeling Bride and Groom. After the Lasso, the Veil is placed over the shoulders of the Groom and the shoulders or head and shoulders of the Bride. It may have to be pinned in place in order to stay. Thus tied together symbolically, the couple remains kneeling for the prayer. After the prayer and before either attempts to rise, at the end of the ceremony, the lasso is removed by the same people who put it on and given to the bride as a memento of her becoming the mistress of the groom's heart and home.
