What Is Interfacing in Sewing?

Non-woven Interfacing

Non-woven interfacing is one of the many materials available for use in sewing. The fabric used is typically a light cotton/rayon blend. Thicker interfacings can be made from 100% polyester.

Both are available in a range of weights. Some types of interfacing can be cut in any direction, while others are made of a combination of fabrics.

Interfacing has many uses and can become an indispensable part of your project. The most common use is to give garment parts such as collars and lapels structure. It also gives cuffs and hemlines shape and stiffens light or thin fabric.

In addition to clothing, it can be used in home decor projects as well.

Non-woven interfacing is also easier to cut. It can be cut in any direction, making it less likely to cause waste. However, if you are fusing non-woven interfacing with fabric, the result will be a stiffer, unflattering garment.

In addition, non-woven interfacing may cause creases and crinkles on the right side of the fabric. In short, woven interfacing is more durable and always looks and feels better.

Sew-in Interfacing

When you’re sewing, you may want to use sew-in interfacing. This kind of interfacing can be attached to either an outer or lining fabric. This way, it won’t show when the final garment is finished.

To attach this type of interfacing, you must use straight pins and a stitch length of at least 5/8 inch.

There are two types of sew-in interfacing:

  1. Woven and
  2. Non-woven.

Weft interfacings are typically used for heavier fabrics or garments. Fusible tricot is a lightweight alternative and works well with knit fabrics.

Fusible fleece can also be used to add quilting details to apparel. Another type of interfacing is horsehair, which is used for tailoring. This type of interfacing can be machine-washed, tumble-dried, or dry-cleaned.

Weaved interfacing is the most common type of interfacing for sewing. It looks and moves like regular woven fabric. It also has a selvedge and grainline. However, it is a bit more difficult to work with and is usually reserved for fine materials.

Silk Organza

When you use silk organza interfacing in sewing projects, you’re adding an elegant layer to your projects that won’t lose shape and drape as easily. It gives your clothes structure and helps stabilize necklines and armholes without weighing them down.

Unlike polyester interfacing, silk organza is lightweight and can be hand-basted to the fabric before sewing.

Silk organza interfacing is a lightweight nonwoven fabric that has a smooth, crisp hand feel. It can be used with all types of fibers.

It is ideal for creating a variety of clothing pieces, including home decor, bridal wear, and apparel. Its soft hand feels won’t scratch skin and makes it easy to manipulate.

While there are different types of interfacing, silk organza is the best option for most projects. If you’re using charmeuse fabrics, you should use silk organza interfacing if you want crispness or a softer hand.


When you need to use self-fabric interfacing in sewing, you need to know what you’re doing. You need to determine which pieces of a pattern will require interfacing and set aside those pieces while you cut the main fabric.

Then, cut the interfacing pieces with the proper grain and the appropriate amount of width. If you’re using a thick fabric, you may need to cut the interfacing pieces a bit smaller. You can buy interfacing by the yard, or purchase it in pre-cut packages.

Most interfacing comes in a narrower width than fabric.

Self-fabric interfacing is available in a variety of weights. Some of the most common types are woven and non-woven. Woven interfacing has the advantage of good drape and is easy to work with.

Woven interfacing is also available in stiff forms. These types look and feel like paper, and should be cut on the same grain as the external fabric.
