Abstract
The nonroll selvage of the crew or athletic sock includes a plurality of rounds of polyurethane elastic yarn and a single course of plain stitch loops knit solely of a stretchable yarn to form single yarn stretchable stitch loops alternately positioned in front of and behind the rounds of polyurethane elastic yarn. The stretchable yarn connecting the upper ends of adjacent stitch loops of this single course passes over and surrounds the rounds of polyurethane elastic yarn in contracted condition so that the rounds of polyurethane elastic yarn are drawn together and held closely against the first course of the portion of the leg adjacent the nonroll selvage to provide a small upstanding bead extending around the upper end of the sock.
