The bobbin case of this machine threads as they do on most machines, hold the bobbin case in your left hand, with the open end facing to the right. Hold the bobbin in your right hand with the end of the thread going away from you. Put the bobbin in the bobbin case and pull the thread through the slot in the bobbin case and under the tension spring. That's the bobbin case threaded.
