15K Universal Plastic Domestic Sewing Machine Bobbins fit most front-loading machines. Check the machine manual for the correct Bobbin.

Plastic bobbins and metal bobbins of the same size should NOT be swapped. Machines are set for very precise tension settings. If they are set for a lighter plastic bobbin, the tension will change if a heavier metal bobbin is used.

• Use only bobbins that are the same class/style as those that come with your machine – don’t substitute!
• Wind thread on empty bobbins only – don’t wind additional thread onto partially wound bobbins, as this can cause stitch irregularities when you sew.
• Don’t overfill bobbins or they will not move freely in the bobbin case.
• Make sure the thread is correctly seated in the bobbin winding tension disk of the machine before starting to wind (see your machine instruction manual for more information).  The thread that is wound too loosely can cause machine jamming.  The thread that is wound too tightly can distort or break the bobbin.
• If a bobbin becomes chipped, bent, warped or damaged, discard it & replace it with a new bobbin.
