What is interfacing? It is the inner construction material that lies between layers of fashion fabric. It adds shape, strength, and body to every project and many garments require some type of interfacing. You can find it in collars, cuffs, waistbands, lapels, necklines, button holes, and any opening that needs additional stability or support.
There are three different types of interfacing non-woven, woven, and knit. These types come in either fusible or sew-in applications and come in different weights and colors. A rule of thumb to follow when choosing interfacing is to always choose a weight that is the same or slightly lighter than the fabric you are using. Let’s take a closer look at the three types and applications of interfacing.
Woven interfacing has a lengthwise and crosswise grain just like woven fabrics. Matching the grain of the interfacing with the grain on the fabric is a crucial part to make sure the two layers work together properly. Due to the matching grain requirement of woven interfacing this may have to be cut on the bias. This tends to be stronger and more stable than non-woven interfacing. Woven tends to be used for more tailored garments.
Non-Woven interfacing is made of bonding or felting fibers together, creating a mesh without visible direction and therefore has no grain. This type can be cut in any direction, it won’t ravel and is very easy to use. The only fabric that can’t be used is a stretch fabric, like jersey knit.
Knit interfacing is usually soft and flexible with a stretch crosswise, but minimum lengthwise stretch. This type is suitable for garments using jerseys and other stretch fabrics as it will stretch with the garment and not hinder it. Knit interfacing can be used on woven fabrics when you want a softer shape or when you want to maintain stretch in the fabric after the interfacing has been applied.
When it comes to the application of interfacing there are two kinds; sew-in and fusible. All three types of interfacing are offered in both applications. Knowing the type of fabric being used will help to select the correct application of interfacing to give the shape and body that is needed.
JOANN also carries specific interfacings for certain projects. When working with draperies or accessories using a craft or home decor interfacing is recommended. There are interfacings specific to select quilting projects. Fusible web bonds two fabrics together. This is great for appliques and other craft projects. For those that embroider there are special interfacings to help stabilize the threads.
