Dupioni generations. The major demands of the Indian wedding industry are met by this city. Dupioni Dupioni (also referred to as Douppioni or Dupion) is a plain weave crisp type of silk fabric, produced by using fine thread in the warp and uneven thread reeled from two or more entangled cocoons in the weft. This creates tightly-woven yardage with a highly-lustrous surface. It is similar to shantung, but slightly thicker, heavier, and with a greater slub (cross-wise irregularity) count.

An interesting case of ingenuity under wartime adversity was the Colditz Cock glider. This homebuilt aircraft, intended as a means of escape, employed prison bedding as its covering material; homemade glue and dope made from boiled millet were also used by the prisoners in its construction.
