Sewing Machine Bobbin:
- The bobbin provides the thread for the underside of the stitches a sewing machine forms.
- Bobbins are not interchangeable between sewing machines.
- Bobbins are filled on the bobbin winder and the thread should be evenly distributed on the bobbin.
- It is advisable to have extra bobbins for your sewing machine so that you don't find yourself unwinding bobbins to change the color of the thread on the sewing machine.
