* * *In the simplest twill, the weft crosses over two warp yarns, then under one, the sequence being repeated in each succeeding shot (row), but stepped over, one warp either to the left or right. In regular twill, the diagonal line is repeated regularly, usually running upward from left to right at 45°. The weave can be varied in many waysfor example, by changing the direction of the twill line (as in herringbone twill) or its angle. Twill is much used for men's wear and many other clothing applications because it has stretch on both diagonals, which makes clothes comfortable even if closely fitted. Denim and many tweeds are of twill weave.
