Visual determination of unevenness along the length of a yarn is carried out by wrapping it in equally spaced parallel wraps over a board and comparing the appearance of irregularities against standard rating photographs. To enable yarns of different thickness to be assessed, the spacing between the warps is suitably selected so as to give a clearly distinguishable pattern.
