Fabric shrinkage

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.

Dampening or steaming a piece, especially a knit, and pinning it to dry in a set shape and dimension to correct distortion before or after construction.

A fabric's resistance to fading or bleeding dye during washing, light exposure or rubbing, tested before combining contrasting fabrics in one garment.

A garment-cleaning process using chemical solvents instead of water, required for fabrics that distort, shrink or bleed dye when laundered, such as wool suiting and structured silks.

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.
