A method of knitting an elastic drawcord product and an elastic band and drawcord composite product are described. The method involves knitting a pair of elastic webs in a laterally spaced relationship to each other, and securing a drawcord within the space between the elastic webs by way of first and second tying yarns. The first tying yarn reciprocates across the space between the first and second elastic webs and is alternatingly secured to the side edges thereof along the front face of the elastic webs. The second tying yarn reciprocates across the space between the first and second elastic webs and is alternatingly secured to the side edges thereof along the rear face of the webs, and the drawcord is secured between the two elastic webs and the first and second tying yarns. The tying yarns can be reciprocated for a number of courses, then held along the side of one of the webs for a predetermined number of courses before resuming reciprocation, to form sets of tie legs which cover spaced apart portions of the space between the elastic webs. The elastic drawcord product can be integrally formed on a knitting machine with the drawcord being inserted while the elastic threads in the elastic webs are in an extended form, to provide a drawcord with an effective length which is longer than that of the elastic band in its unextended condition.
