What Is Interfacing Fabric?

Interfacing is a material that alters the characteristics of existing fabrics. Generally speaking, Interfacing is soft and structured. This material is added to sewing, quilting, or craft projects to add body, stability, thickness, weight, and comfort, among other characteristics.

Types Of Interfacing Fabric?

Interfacing comes in many different styles and types. Interfacing can be manufactured in various ways with different materials. Sourced or blended from various fibers, synthetically made interfacing can be more affordably priced, while naturally sourced ones are hypoallergenic.

Furthermore, these fabrics can feature an adhesive backing for easy application. Interfacings can also be woven, knit, or non-woven, in addition to having various weights. Combined with the fibers used, each type of Interfacing is different.

Let’s discuss each type of Interfacing more in depth:

    • Woven Interfacing

      Woven Interfacing is a non-stretchy type of interfacing that displays an elegant woven appearance. These interfacing fabrics are usually woven from any fibers, can feature a fusible backing, and are made in a 1-over-1 style weave. This manufacturing method gives Woven Interfacing a grainy appearance, subtle texture, and no stretch except for a minor mechanical stretch on the bias.

    • Knit Interfacing

      Knit Interfacing is a stretchy and very soft material that displays stylish knit stitching. This type of Interfacing fabric can be sourced or blended from any fiber, feature an iron on backing, and are knit instead of woven. This makes Knit Interfacing extremely soft, elegant in appearance, and stretchy.

    • Weft Interfacing

      Weft Interfacing is a very soft and elegant-looking type of interfacing that has a stylish appearance. This fabric is first knitted, then threads are woven in between each knit stitch. Due to this process, Weft Interfacing is soft like a knit interfacing, but does not stretch like a woven interfacing

    • Non-Woven Interfacing

      Non-Woven Interfacing is a type of interfacing that has a felted appearance, paper like texture, and no stretch. This fabric is made from various fibers which are compressed together, giving it a fibrous texture and appearance, in addition to making it very easy to cut without causing any fraying

How To Choose An Interfacing Fabric??

Choosing the correct type of Interfacing can seem like a daunting task, but with the right know-how it is not that hard. When picking an interfacing, consider these three things: the fabric type, the fabric weight, and the application. The qualities of the interfacing should usually match the qualities of the fabric being used. For example, when using a stretchy fabric, you will want to use a stretchy interfacing, and vice versa.

Additionally, consider the weight of the fabric when selecting an interfacing. A lightweight fabric should be paired with a lightweight interfacing, while a heavyweight fabric should be paired with a heavyweight interfacing. Furthermore, the application of the fabric will dictate which interfacing should be chosen.

How To Apply Interfacing Fabric?

Interfacing can be easily applied to most textiles. There are two ways to apply interfacing depending on how it was made. Some Interfacings contain a fusible, adhesive backing which can be easily ironed onto most fabrics, while Interfacings that do not, must be sewn in. For the most part, both interfacings can be used interchangeably, with the only difference, being the additional work and materials required to sew the interfacing.
