Quarter Tag
Like tag the line, except the dancers stop walking forward when the original centers from each side of the line meet.

Any line with an even number of dancers.

Facing lines with pass thru, tag the line full, 8 steps; three quarters, 7; one half, 6; one quarter, 5 steps. Two-faced line tag the line full, 6 steps; three quarters, 5; one half, 4; one quarter, 3.

Arms in natural dance position, hands ready to assume appropriate position for the next call. A flowing type of movement can be achieved by taking a slight step forward before turning toward the center of the line, thus avoiding the abrupt military type pivot.
