What is the use of interfacings?

An interfacing is used to stabilize a garment in some crucial places such as around the neck opening and armholes, sometimes even on hems. Interfacings are most often iron-on and it is ironed onto the facings and will be completely hidden.

using interfacings will elevate the look of a garment by going from a "home-made" look to a professional look. Facings come in different weights and contents, start by using a light to medium weight woven interfacing and experiment with knit facings as you learn the craft of sewing.
