A short encyclopedia entry defining bays as a coarse, open woollen fabric with a long nap, woven on a two-treadle loom like flannel. It covers the centers of manufacture (Colchester and Bocking in Essex, and Lisle and Tournay in Flanders), the introduction of the trade to England by Flemish refugees under Elizabeth I, and the decline of exports as French makers imitated it. It also gives the uses and standard widths and lengths of bays.
