Abstract
A fiducial for use in the manufacture of a fabric article includes a hole through a layer of fabric. Another layer of fabric of the fabric article overlays and obscures the fiducial. The fiducial is detected by transmitting electromagnetic radiation through the fabric article. The electromagnetic radiation may make a single pass directly through the fabric article to a sensor, or may pass through the fabric article, be reflected off a surface, and pass back through the fabric article to the sensor.
