Blocking (textile arts)

Through heat and moisture, blocking sets the stitches and standardizes the final dimensions, and may enhance the drape.

[1][2] Hand manufacture places natural stresses on fabrics that may result in deviations from its intended shape and size.

The degree of malleability is determined by the type of yarn used, with wool providing the most flexibility.

[5] Wet blocking is done by saturating a garment in warm water and allowing it to dry.

Hovering the iron about 1 or 2 inches above the fabric flattens the stitch, makes it thinner, and allows it to hold its shape better.
