This invention relates to a method of knitting a fabric
on a “full-fashioned” knitting machine in such a manner
as to form a type of vari-colored pattern which hereto
stantially inextensible, such as nylon, rayon, cotton or
silk, and being of smaller diameter than the extensible
yarn 20. Each yarn is led through customarily tension
devices such as those shown at 15, 17 and 19 in FIG
URE 2 by which the yarns are under tension when they
emerge from the carrier tubes 12 and '14.’ Since the
yarn carrier travels back and forth along the? needles,
10 the rubber yarn will lead when the carrier is moving in
one direction and the other yarn will lead when the car
rier is moving in the reverse direction so that the rub
