Jacket block
      This block eliminates shoulder and armhole 
        seams while maintaining arm lift.  
      This ´shell´ provides a basis for 
        many variations in yoke lines and the degree 
        of arm lift, and elbow articulation, can be 
        varied according to the posture of the intended 
        end use.  
      The block is close fitting and appropriate 
        for two or three layer shell garments. 
       The example given is drafted to standard mens´s 
        size 100 cm chest without seam allowance included.
