Abstract
Abstract This stocking is knit on a circular hosiery knitting machine and the upper end of the leg is provided with an upstanding and integrally knit extension with a narrow elastic band extending around the remaining portion of the upper end of the leg portion. Opposite ends of the elastic band are attached to opposite sides of the extension. The upper section of the leg portion, immediately below the band and the extension, is knit with alternate courses of covered spandex yarn and intervening courses of stretchable textured yarn. The spandex yarn and stretchable yarn are both alternately knit and tucked to provide a circumferentially enlarged area in this upper portion of the leg of the stocking.
