From a two faced line: Centers arm turn 3/4 and spread. Ends Partner Tag and quarter right or left (as per the call) and then Diamond Circulate. Points then Flip into nearest center of a wave or two faced line.
COMMENT: Dancers have difficulty identifying themselves as points or centers of a "diamond" here. Rotary Tag/Spin Tag movements are really "Top" type moves rather than "Diamond" moves.
