Divide the overall formation along its long axis into planes of dancers
  (e.g., a 1 x 8 has eight planes; a 2 x 4 has four planes).  Dancers
  occupying every other plane work together to do the given call.  At the end of
  the given call, the dancers in one set of planes must end within their
  original set of planes.
| |   |  |   |  | From a 2 x 4, the Once Removed dancers
 are in a 2 x 2
 |  | From a 1 x 8, the Once Removed dancers are in a 1 x 4
 |  |  |  |   |  |   |  | From here, the Once Removed dancers are in a Diamond
 (or Single 1/4 Tag)
 |  | From here, the Once Removed  dancers are in a Diamond (or Single 1/4 Tag), whereas
 the Once Removed
  dancers are in a 2 x 2 |

At C2, Once Removed is primarily limited to doing simple 
  (i.e., non-shape-changing) calls from a 2 x 4 or a 1 x 4.
  From a 2 x 2, the dancers work in a manner similar to working in
  (Interlocked) Blocks [C1].
See 
  Block FORMATION [C1]
  for a list of non-shape-changing calls from a 2 x 2.

Sample traffic patterns:
  - Once Removed Right & Left Thru
  
    - From (starting) Double Pass Thru.  Centers Pass Thru; all Right
        Pull By; New Centers Pass Thru; all Courtesy Turn.
    
- From Facing Lines.  All Right Pull By; Centers Half Sashay; 
        all Courtesy Turn; Centers Half Sashay.
More sample traffic patterns:
  - Once Removed Square Thru
  
    - This is done as if in Blocks [C1].  I.e., do each Pull By
        with the appropriate dancer (go to their spot) and then Face In.
    
- From Facing Lines. Right Pull By; Face In; Centers (Left-shoulder)
        Pass Thru; all Left Pull By & new Centers (Left-shoulder) Pass
        Thru; all Face In; Right Pull By; Face In; Centers (Left-shoulder)
        Pass Thru, all Left Pull By & new Centers (Left-shoulder) Pass
        Thru.  Ends in Completed Double Pass Thru.
    
- From Double Pass Thru: Centers Pass Thru; all Right Pull By; Centers
        Pass Thru; all Face In; Left Pull By Face In; Centers Pass Thru;
        all Right Pull By; Centers Pass Thru; all Face In; Left Pull By.
        Ends in Back-to-Back Lines.
  - Once Removed Square Chain Thru
  
    - Since 
        Square Chain Thru [A1]
        is an intricate call,
        start the call Once Removed, finish the call on
        each side, and then have the new Centers move to the other side.
    
- From Facing Lines.  Right Pull By; Face In & Centers Pass Thru;
        all Left Swing Thru; Left Turn Thru; Centers Pass Thru.  Ends in
        Completed Double Pass Thru.
    
- From Double Pass Thru.  Centers Pass Thru; all Square Chain Thru;
        Centers Half Sashay.  Ends in Back-to-Back Lines.
Notes:
- 
Immediately after hearing the words 'Once Removed',
    determine the wall toward which your Once Removed setup is closest,
    and make a visual note of which dancers are in your Once Removed
    setup so that if the call is a shape-changer you will know who should
    belong in the resulting Once Removed setup.
 CONTRAST THE FOLLOWING (don't panic...this usage is only done at C3 or above.)
| |   |  | This is the starting formation for each of the following:
 |  |  |  |   |  |   |  | after As Couples Once Removed Hinge
 |  | after Once Removed As Couples Hinge
 | 
 | 
In the first example, As Couples precedes Once Removed, hence you
  must first establish who is Couples with whom 
  (  and
 and  act as one dancer;
 
  act as one dancer; 
   and
 and  act as one dancer, etc.) and then work Once Removed (hence
 
  act as one dancer, etc.) and then work Once Removed (hence 
  
 is working with
 
  is working with 
  
 ).
 ).
In the second example, Once Removed precedes As Couples, hence you
  must first establish who is in your Once Removed setup 
  (  ,
,  ,
, 
   , and
, and  are in one setup;
 
  are in one setup; 
   ,
,  ,

  and then work As Couples (hence
 
  are in the other) 
  and then work As Couples (hence 
  
 is a Couple working with Couple
 
  is a Couple working with Couple 
  
 .).
