From a 2 x 4.
Do a total of four Split Circulates, except that when you become an
In-facing Center do your next Circulate to your diagonal opposite position
(crossing over into the other Box). Exchange The Box can be
fractionalized into fourths.
Traffic pattern: when crossing to the other Box, stay outside of those who are still in their
original Box. The In-facing Centers lead the Exchange and, from a normal setup, everyone
else in their Box can follow them.
Dancing hint: Those leading the exchange should raise a hand to identify
themselves so that the other dancers in their Boxes can follow them.
