  through original shoulder
 When replacing seam
  allowance make sure new
  corner stays on this line.
   Angular Adjustments-

• Varying shoulder slopes are
  extremely common.
• Below is a common standard.
                                Look for U shaped
                                wrinkle or stress in

  corner, and underarm corner.
