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. Using SINGER Bobbins is simple: wind your thread onto an empty bobbin, ensuring it is correctly seated in the bobbin winding tension disk of your machine. 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 3-pack of 12 SINGER Class 15J Transparent Bobbins delivers professional results with ease.
