Tweed is a rough, unfinished
woolen fabric, of a soft, open, flexible texture resembling
cheviot or homespun, but more closely woven. It is made in either plain or
twill weave and may have a check or
herringbone pattern. Subdued, interesting color effects (heather mixtures) are obtained by twisting together differently colored woolen strands into a two- or three-ply
yarn.
