From a Line or other applicable 4dancer formation.
Centers Step Ahead as Ends Run into the adjacent Center position.
Ends in either a Box (2 x 2) or a "Z" (4 spots within a 2 x 3 Matrix).
Step & Flip is similar to
Step & Fold [C1]
except that on a Step & Flip the original Ends always finish holding
hands with each other.

Notes:

From a Wave, Step & Flip ends in a "Z" whereas
Step & Fold
ends in a MiniWave Box.

The 'Step' of Step & Flip is a step ahead, which often (but not
always) is the same as a Press Ahead. 'Flip' means Run into the
adjacent position (as in Flip The Diamond).

Unlike
Step & Fold,
Step & Flip can be done from any line of 4.
Upon completion of the call, the original Ends are adjacent to each
other. From Parallel Lines, Step & Flip is done in each Line, and
nobody crosses the center line to the other half of the set.
