A 1927 German-language article by Richard Hünlich on reinforcing or thickening fabrics by layering thread systems, and on how to analyze such fabrics. It describes three types: warp doubles (extra backing warp), weft doubles (extra backing weft), and double cloths, with guidance on choosing ratios of face to backing threads and on stitching the layers together invisibly. It also explains how to design the weaves on point paper and how to dissect a sample to determine the weave. The scan opens with the end of an earlier piece on ice-pattern (Eisbindung) fabrics with color-and-weave striping and check effects, and closes with a page of jacquard pattern designs.
