A short encyclopedia entry defining crape as a light, transparent, gauze-like silk fabric made from raw silk that is gummed and twisted on the mill, and used chiefly for mourning. It explains the difference between crisped (double) and smooth (single) crape, how the crisping results from heavier twisting of the warp, and mentions its origin in Bologna, manufacture at Lyons, and a historical reference to St. Bathilda's crape of gold and silver.
