SINGER Class 15J Threaded Bobbins in Case, 12-Count, Black & White

Enjoy the flexibility to switch between threads seamlessly with the pack of 12 SINGER Class 15J Transparent Bobbins, featuring 6 pre-wound bobbins with black thread and 6 with white thread. Each bobbin provides 50 yards of durable, washable, and colorfast sewing thread, making this set a must-have addition to your sewing supplies, perfect for both novice and expert sewers. Class 15J bobbins are slightly curved and smaller than Class 15 bobbins, and should not be used interchangeably. They are commonly used in home sewing machines for various sewing projects, from simple repairs to complex garment construction. These versatile bobbins are compatible with a wide range of sewing machines, including select SINGER, Atlas, Brother, Domestic, Elna, Kenmore, Morse, Necchi, New Home, Pfaff, Sewmore, Universal, White, and Wizard sewing machines. Please consult your machine’s manual to determine compatibility. In machine sewing, the bobbin thread forms the bottom part of your stitches, working with the top spool thread for strong, consistent stitches. Made from high-quality plastic, these bobbins ensure smooth thread winding and unwinding, preventing stitch irregularities and machine jamming. For best results, use bobbins that match the class/style of those that come with your machine and wind thread onto empty bobbins only, ensuring proper tension. Replace any bobbins that become chipped, bent, or damaged. Whether you're creating clothing, quilts, or DIY home décor, the pack of 12 SINGER Class 15J Transparent Bobbins, pre-wound with black and white thread, delivers professional results with ease.
