In this lesson, you’ll learn exactly when and how to apply interfacing so your garment has the structure, stability, and polish it deserves—and learn the simple trick to prevent the dreaded bubbling or puckering. Even though our Foundation Skirt doesn’t use interfacing, we’ll practice the technique on a scrap, because interfacing is essential for almost every skirt design you’ll sew moving forward. You’ll explore two different methods for cutting and fusing interfacing.
