Oh, and coincidentally, I've just opened the copy of Francis Pryor's The Making of the British Landscape that I happen to have in my bag and there, on page 531 (Penguin Edition), is a picture of hand-weavers' houses in Saddleworth with the long upper windows. He also discusses the Luddites and the working practices of the hand weavers at the time when "...yeoman clothiers, who might have been wealthy farmers keen to diversify....would both supply yarn and buy in spun cloth from hand weavers."
