From columns: The first 3 dancers in each column do the Promenade part of Transfer the Column, and the
#4 dancer Extend (to meet the other #4 dancer), Cast Off 3/4, and Extend. Finishes in 3-and-1 lines. On the
Extend, the lone dancer steps to a mini-wave with the center of the outside threesome, using the same hand
used in the Cast.
