From a line: To Cast Right, the right side person in each couple acts as a pivot and the left side person walks forward to turn as a couple the indicated fraction. To Cast Left, the left side person in each couple acts as a pivot as the right side person walks forward to turn as a couple the indicated fraction. If the call is Cast Right/Left 1/4 or 3/4, the move finishes with one couple behind the other; if the call is Cast Right/Left 1/2, the move finishes in a line.
