ca. 1750; England; Frame-knitted silk These stockings were knitted as flat pieces using stocking frames operated by male workmen. The foot or sole sections were knitted separately. The two pieces making up each stocking were then sewn together by female workers. Decorative areas at the ankles, called clocks, were either put in during the knitting process, as in these two examples, or embroidered after the stocking was taken off the frame.
