Bobbin is not feeding properly- didn't wind on evenly.
It is important that the bobbin be wound smoothly for the machine to operate properly. First, check that you are threading the machine correctly to wind the bobbin. There is a tensioner for the bobbin winder that helps wind the bobbin smoothly so incorrect threading will cause issues. Also, try to wind your bobbin slower. There is no advantage to winding the bobbin on high speed.
If you continue to have bobbin winding issues, there is a standalone bobbin winder (SideWinder) avlb at JoAnn's or even Amazon for ~$30,. They are electric or battery operated. Be sure to verify your machine bobbins will work on the SideWinder before purchasing as some bobbins are not compatible. The bobbin winder is a handy gadget since multiple bobbins can be wound quickly, plus bobbins can be wound without having to unthread the machine, not to mention reducing the wear and tear on your sewing machine.
