 Command:  Options/Modes/Warp-Face Packing        < OMA > 
 Purpose:  SWITCH--Control warp-face weaving mode
 Information:
     The Weave Cycle number of warp threads are packed into a 
     single column of color- or symbol-generated pattern.

     The Warp Limit must be evenly divisible by the Weave Cycle;
     Patternland will issue an error message if it isn't.  You 
     can then change the Weave Cycle or more likely add or 
     subtract warp threads.

     Usually, no weft shows in a warp-face weave such as an 
     inkle loom type belt.  To achieve this, the weaving must 
     have a highly regular threading and the treadling usually 
     matches it.  Use Tromp-as-writ to copy threading to 
     treadling. 
     
     The basic requirement Patternland makes is that the same 
     threading harness cannot be used twice within the same Weave 
     Cycle of threading.  If that happened on a loom the threads 
     might bunch up and the weft would show through. In 
     Patternland, the color/symbol of the first of the duplicates 
     would be overwritten by the second--and Patternland would 
     "hide" the color/symbol of the first thread, no longer 
     providing a true simulation. 
 Comments:
     Turn Warp-Face Packing OFF to print or display an "unpacked" 
     pattern draft which can show the threading and treadling. 
     
     Multi-Symbol or Color Weave modes must be selected for warp 
     face weave mode to function.

     EXAMPLE
     In the 4-cycle example below, note that NO WARP THREAD USES 
     THE SAME HARNESS AS ANOTHER within a cycle group of four.
     Weft symbol is the default single symbol: "=".  Warp symbols 
     are W X Y Z.  20 warp threads pack horizontally to produce 5 
     pattern columns.

 Command:  Options/Modes/Weft-Face Packing        < OME > 
 Purpose:  SWITCH--Control weft-face weaving mode
 Information:
     The Weave Cycle number of weft thread rows are packed into a 
     single row of color- or symbol-generated pattern.

     The Weft Limit must be evenly divisible by the Weave Cycle;
     Patternland will issue an error message if it isn't.  You 
     can then change the Weave Cycle or more likely add or 
     subtract weft threads.

     Usually, no warp shows in a weft-face weave such as a 
     tapestry.  Opposite to warp-face, the weft is made visible 
     through NON-matching of warp threading and raised harnesses.  
     To achieve this, the weaving must have highly regular weft 
     harness combinations (treadling).  The threading is not 
     constrained; a regular matching threading like the example 
     below produces vertical stripes. 
     
     The basic requirement Patternland makes is that the same 
     weft harness cannot be UNused twice within the same Weave 
     Cycle of weft.  If that happened on a loom the threads 
     might bunch up and the warp would show through.   In 
     Patternland, the color/symbol of the first of the duplicates 
     would be overwritten by the second--and Patternland would 
     "hide" the color/symbol of the first thread, no longer 
     providing a true simulation. 
 Comments:
     Turn Weft-Face Packing OFF to print or display an "unpacked" 
     pattern draft which can show the threading and treadling. 
     
     Multi-Symbol or Color Weave modes must be selected for weft- 
     face weave mode to function.

     EXAMPLE
     In the 4-cycle example below, four weft rows pack together 
     to make a single visible pattern row produced by varying the 
     thread colors or textures (symbols).  Note that NO HARNESS 
     IS DOWN TWICE within each cycle of 4 rows.  Warp symbol is 
     the single symbol: "|".  Weft symbols are W X Y Z.  8 weft 
     threads pack vertically to produce 2 pattern rows.

 Command:  Options/Modes/Weave Cycle to Pack      < OMW > 
 Purpose:  SETTING--Determine the packing cycle value
 Information:
     In Warp- and Weft-face Weave modes, the Weave Cycle number 
     of threads are packed into a single line of color- or 
     symbol-generated pattern. 
 Comments:
     The total warp or weft must be evenly divisible by the 
     packing cycle you set.
