Winding and Inserting the Bobbin

You’ve threaded the needle, so next just pop the bobbin in its case and you’re ready to sew.

  • Check the bobbin tension by pulling the thread. It should have some resistance without unwinding.
  • Make sure it is turning clockwise when sewing.

Raising the Lower Thread

Once your bobbin is wound, you’ll have to gently pull that thread up between the tension discs before lowering the presser foot and getting to sewing. Make sure the pressure foot is up, lower the needle into the fabric while tucking the threads under the foot.
