Woven fabric
A fabric made by interlacing lengthwise threads (the warp) and crosswise threads (the weft) at right angles.
Woven fabrics such as poplin, denim, twill or gabardine barely stretch in the direction of the threads unless they contain elastane. They fray at the cut edges and need seam finishes. Patterns for wovens carry more ease and darts or other shaping, because the fabric does not stretch to fit the body, while patterns for knits are cut smaller than the body measurements.
Example
A poplin shirt needs darts or a yoke for shaping, and ease, because the cotton fabric does not stretch.
