The herringbone weave encompassed any weave woven in a zigzag pattern to create chevrons. In the 18th century it was often found in linen tickings and other hard wearing linens. In the 19th century the weave found its way into other textiles including wool. Wool "flannels" in the 18th century consisted of a woolen yarn slightly twisted in the spinning and woven in plain or twill weave and then lightly brushed. This created a soft, spongy wool, not extremely sturdy but useful for a variety of purposes such as petticoats, gowns, under-waistcoats, jackets, children's clothing etc. When fulled, flannel would become very lofty creating a soft but thick fabric.
