From Facing Lines, Eight Chain Thru, or other applicable formations.
  - Cross Trail Thru;
- Centers Trade as Ends U-Turn Back by turning away from the
  Center (i.e., 1/4 Out & Roll).
Facing Lines end in Facing Lines; Eight Chain Thru ends in Eight Chain Thru.
Cross The "K" is a 2-part call.
Notes:
- 
Remember that Cross Trail Thru [A1] is a Pass Thru and Half
    Sashay.  You end back-to-back without changing your facing direction.
- 
If you become an End, be sure to U-Turn Back by turning away from
    the Center.  The caller could add a Roll (in which case the
    Ends finish facing in after the Roll).
