Sophie's Socks

The structural design of knitted socks and stockings has changed very little from when they were first knit centuries ago. Then, as now, the logical way to make a knitted article that covers part of the leg and foot is to connect two tubes at an angle-one tube with an open end; the other with a closed end. Part of the art and the pleasure of knitting socks centers around the area where the two tubes connect, known as the heel. From “Folk Socks” by Nancy Bush
