Wind heavier threads onto the bobbin which are too thick to fit through the needle and sew on the reverse side of the fabric. The Husqvarna Viking/Pfaff Specialty Bobbin Case lets you create beautiful textures and work with fun decorative threads. Includes instructions. You can also use this bobbin case as a replacement bobbin case for regular sewing, it is colored grey only to distinguish it from the standard bobbin case.
