From a line of three with man in the middle (See Tie The Knot): Without letting go of hands, the girl on the right crosses to the left outside with inside hands held high, the girl on the left crosses to the right inside, ducking under the right arm of the man. Man makes a half right-face turn until the line of three has reversed direction. Now the procedure is reversed. Holding left arm high the man leads the left hand lady across to the right outside and leads the right hand lady across to the left inside and under the raised arm. Man makes a half left-face turn until the line of three is facing original direction again.
