NOTE: This is NOT a Right And Left Roll. The "Quarter More" applies to couples, not to individuals in this case.
From facing couples: Do a normal Right and Left Thru but continue the courtesy turn another quarter until girls are shoulder to shoulder in the center in a two faced line. Finishes in a two faced line at right angles to the outside couples.
