Fabrics & materials

A folded strip of bias fabric enclosing a cord, inserted into a seam to create a raised decorative or defining edge along garment seams.

The simplest weave structure, formed by alternating single warp and weft threads over-under, producing a strong, stable, balanced fabric such as poplin or muslin.

A synthetic petroleum-based fibre valued for durability, wrinkle resistance and low cost; woven or knitted alone or blended with natural fibres.

A durable, easy-care lining fabric made from polyester fibre, resistant to wrinkling and shrinking though less breathable than natural-fibre linings.

An all-purpose sewing thread with high strength, low shrinkage and good elasticity, suitable for most woven and knit fabrics including synthetics.

A medium-weight double-knit fabric, usually of polyester, viscose and spandex, with a firm hand and good stability, popular for structured knit garments.

A tightly woven plain-weave cotton or cotton-blend fabric with a fine crosswise rib, crisp yet soft, popular for shirts and dresses.

Laundering fabric before cutting a garment to remove sizing, allow shrinkage, and test colourfastness, so the finished garment behaves the same way as the fabric was tested.

Treating fabric, interfacing or trims with heat or moisture before cutting so later shrinkage does not distort a finished garment.

Using an iron with an up-and-down motion, rather than sliding, to set seams, creases and shape during construction, done at each stage rather than only at the end.
