Fabrics & materials

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.
