From any Line of 4.
Ends Cross Fold while holding onto adjacent dancers.
A Wave ends in a Mini-Wave Box.
Notes:
- 
Although Ah So can be called from any Line of 4, it is
    almost always called from a Wave.  In fact, many callers
    believe Ah So can only be done from a Wave.
- 
From a Couple, Ah So is equivalent to Wheel & Deal.  From a
    Mini-Wave, Ah So is equivalent to Single Hinge & Box Counter
    Rotate 1/4.
- 
Ah So is a generalization of Wheel & Deal.  If both Ends
    are initially facing the same direction, the rightmost End moves in
    front of the leftmost End (as they would in a Cycle & Wheel starting
    from the same setup).

I've also seen Ah So done from the following T-Bone setup, in which case
  the Ends imagine holding onto the Centers' tummies.  I think most callers would
  agree that this example stretches the definition of the call a little too far.
