Twill is a type of textile weave with a pattern of diagonal parallel ribs (in contrast with a satin and plain weave). This is done by passing the weft thread over one or more warp threads then under two or more warp threads and so on, with a "step," or offset, between rows to create the characteristic diagonal pattern.Because of this structure, twill generally drapes well.

Modern canvas is usually made of cotton or linen, although historically it was made from hemp. It differs from other heavy cotton fabrics, such as denim, in being plain weave rather than twill weave. Canvas comes in two basic types: plain and duck. The threads in duck canvas are more tightly woven.

Poplin, also called tabinet (or tabbinet), is a strong fabric in a plain weave of any fiber or blend, with crosswise ribs that typically gives a corded surface.Poplin traditionally consisted of a silk warp with a weft of worsted yarn. In this case, as the weft is in the form of a stout cord the fabric has a ridged structure, like rep, which gave depth and softness to the lustre of the silky surface. The ribs run across the fabric from selvage to selvage.
