Even if you are a beginner you have probably come across the term interfacing or stabilizer in sewing pattern instructions or in sewing blog posts. Interfacing comes in a variety of forms and selecting the right type for a project can be a bit intimidating for the new sewist. Interfacing can be described as a layer added to a garment to add stability, crispness or for longevity. It can simply be an added layer of fabric like muslin or cotton sandwiched between layers of fabric. This type of application would be considered “sew-in” interfacing. Where the added layer must be hand tacked or machine basted to hold it in place. There are many different kinds of sew-in interfacing and some you can buy in yardage as well.
