MODULE 1 • What is Interfacing?

Step Description
1 What is Interfacing?

  • Interfacing is a material applied to certain areas of a garment to add shape, structure and stability
  • Collars, cuffs, pockets
  • Stabilizer on seams, necklines & facings
  • Interfacing should give body, not bulk, to a garment

Interfacing is a material applied to certain areas of a garment to add shape and structure to the inside of the garment such as on collars, cuffs, pockets or areas of a garment as a stabilizer, such as seams, necklines and facings. The most suitable interfacing will add body, not bulk, to a garment.

2A Types of Interfacings

  • Woven, non-woven and knitted
  • Variety of fiber contents and widths
  • Fusible or non-fusible
  • Available black, white & some colors
  • Choose closest color match to fabric
  • Different weights: sheer to heavyweight
  • Chosen for compatibility to garment material
  • Options: a ‘sew-in’ type or a fusible type

Interfacings are available woven, non-woven and knitted. They are manufactured in a variety of fiber contents, various widths and are available as fusible or non-fusible. Most interfacings are offered in black, charcoal and white but some are offered in different colors. Choose one that most closely matches your fabric. Interfacings also come in different weights from sheer to heavyweight and are chosen for their compatibility to the garment material and whether you want a ‘sew-in’ type or a fusible type.
