 One branch of the wool-related trade was cap manufacturing, consisting in the spinning and knitting of caps for headwear.Headwear was an essential part of normal apparel, until the late 20th century.Bell may have made the Tudor beret-style flat cap worn by members of higher society (as illustrated) or possibly the coarser style cap, later known as the "Statute Cap", which was the model approved by the 1571 statute making the wearing of caps compulsory on Holy Days, a measure designed to support the manufacturing industry.
