If you are brand new to sewing, interfacing might seem a little mysterious. You might even be wondering if you really need it to use it. For a lot of garments you don’t need it but for many it is essential for adding structure to the garment. It is often used on facings, collars, cuffs and button bands to stiffen and reinforce the fabric. Think about ready-to-wear clothing and the areas of the garment that are stiffer than others. These are parts that need to stand up (like a collar), be tough enough to take a buttonhole or simply lie flat along the neckline. Today I’m going to share some basic tips for adhering the interfacing to your fabric. It’s not a hard process but can be a little scary when you first start out.
