Twill Weave

In a twill weave, every weft thread passes over two (or more) warp threads and under one (or more) warp threads, or vice-versa; on the next pick, the weft thread repeats the same sequence-one warp thread to the right for right-hand twill or to the left for left-hand twill.  Twills are easy to identify because threads appear as diagonal in the cloth.
