Simplicity Technical Tip #2
Interfacing

Interfacing is an extra layer of fabric that provides shape and support in detail areas of the garment. Interfacing is frequently used in collars, cuffs, lapels, necklines, pockets, waistbands and opening edges.

Types of Interfacing

The two basic types of interfacings are sew-in and fusible. Both are available in woven, knitted and non woven versions, and in a variety of weights, ranging from heavy to sheer weight. The rule of thumb is that the interfacing should always be slightly lighter in weight than the fashion fabric.
Choosing between a fusible or a sew -in interfacing is really a matter of personal preference. In general, fusibles provide slightly crisper results. Because fusibles “set” the yarns, they’re an excellent choice for fabrics that fray. However, some fabrics do not react well to fusible. These include metallic, beaded, sequined or re-embroidered fabrics, rayon and acetate velvets, most brocades, fake furs, leather, vinyl and openwork fabrics, such as lace and mesh. Always test the fusible interfacing on a scrap of the fashion fabric before you begin to be sure it works and that you like the results.

Most people think of fusible as easier to use and they are, as long as you take time to follow the manufacturer’s fusing directions carefully.
