Right side and wrong side (fabric)

The way a fabric falls, folds and moves under its own weight, ranging from fluid, as in chiffon and jersey, to stiff, as in canvas and taffeta; a key factor in pattern choice.

The diagonal direction across a woven fabric, at 45 degrees to the grainlines, along which fabric has maximum stretch and drape; used for bindings and fluid-cut garments.

The direction of the warp and weft yarns in woven fabric, or the wales and courses in knit fabric, which pattern pieces are aligned to for correct hang and stretch.

A raised, directional surface texture, as on velvet, corduroy or fleece, that reflects light and feels different depending on which way it is stroked; pattern pieces must be cut in one direction.

The tightly woven, self-finished edge running along both lengthwise sides of woven fabric that does not fray, often used as a grainline reference when cutting.
