Interfacing is an important process to use on a sewing project for its ability to add rigidity to the fabric. But, sew-in and fusible interfacing techniques aren’t the easiest to work it. Even though the sewing patterns will give an idea of the options, it can still be difficult to choose the right one to match a specific project.
When is it practical to use interfacing?
Interfacing has the basic process of increasing stiffness to a particular area of clothing, such as a shirt collar, as well as giving greater strength for buttonholes or even to stop certain fabrics from stretching. The most practical option to use is fusible which is applied with the use of an iron to the reverse side of the fabric. Alternative options include the non-fusible interfacing, but this is more time-consuming and needs to be sewn in. Plus, it is more appropriate on fabrics that are loosely woven or unable to tolerate heat. Interfacing also has a use in creating the sewing based home decor.
Fusible vs. Sew in
Fusible interfacing naturally comes with a type of fabric glue on a single side of the material. This glue is quite easy to notice because it feels rough with miniature dots or has a shiny glow. It helps to carefully read the guidelines when attempting to use the interfacing and the application methods can vary. Plus, it is important to avoid putting the iron directly on the glue because it can make a mess and will likely transfer to other items of clothes.
The sew-in interfacing method is the preferred choice when working with fabrics that have a texture or cannot be ironed. There are several techniques that can be used to apply this type of interfacing, such as layering the fabric or basting within the seams.
Pros and cons
Fusible interfacing is the easiest method to use because there is less shifting and only one layer to work with. Fusible is the most effective for giving the solid structure, such as defining the shape of a bag. Overall, this method is a practical choice to make the fabric easier to work with, stronger and thicker. But, it shouldn’t be used on fabrics that are likely to show stretches or creases once the glue has been given time to cool.
Sew-in interfacing is the most difficult method to work with because it relies on working the multiple layers, but it does have the potential to give the more professional finish on lightweight fabrics. Also, there is a low risk of the material creasing with sew-in.
