Abstract
A method for inspecting, detecting and distinguishing sides of fabrics by reflecting light off the fabric and measuring the intensities relatively or absolutely, of such reflected light and comparing such measurements with pre-determined calibrations or other appropriate standards of comparison, so that the fabric can be properly oriented for sewing like sides to like sides, relying on different light reflecting characteristics of the two sides of the fabric.
