Abstract: A method and device for inserting a strand of a selected thread or yarn through the eyelet of a needle, in which the device is made from an elongate, unitary non-metallic monofilament having end zones and an intermediate central zone forming a closed strand-carrying loophole; and the method including the steps of forming the device by bringing the end zones into a parallel relationship and bonding them together to form a threading stem and also form the central zone into the closed loophole, placing an end portion of the selected strand through the loophole, inserting the stem into the needle eyelet, and pulling the threading stem to draw the loophole and strand entirely through the needle eyelet.
