Sometimes you need more tension on the bobbin thread than usual for embroidery, free-motion sewing or free-motion quilting. And that’s why you need the golden-yellow bobbin case.

This high thread tension bobbin case comes standard with the B 500 and B 700.

It will work in the following BERNINA machines:

  • B700 E, B 735, B 740, B 770 QE, B 790, B 790 PLUS
  • B 500 E, B 535, B 570 QE, B 590
  • B 435, B 475 QE, B 480

 

TIPS:

Basing on the higher bobbin thread tension due to the bobbin case, adjust the upper thread tension about 0.5 to 1 higher compared to using the standard bobbin case. Refer to the instruction manual of the machine. 

  • If the bobbin thread is visible on the right side of the fabric, reduce the upper thread tension.
  • If the upper thread is pulled to the wrong side of the fabric too strongly, increase the upper thread tension.
