START: 4-line; two active dancers (centers or ends); shown here: ‘centers cross run’ |
active dancers run into spot vacated by farthest inactive dancer; other dancers sidestep (no change of direction) |
END: centers become ends; ends become centers; only runners change direction; others just slide over |
When active dancers
face the same direction,
they would collide; so first pass each other with a half sashay, then proceed as usual |
memory device: designated dancers cross one dancer and run to the other side |
