The winding methods of sewing machines are generally the same, so I have learned one and understood everything else.

Slowly remove the empty reel, and keep the spring and plunger.

The winding wheel in the handle wheel is pushed inward and rotated to make it pop out.

Pull out the thread rod on the upper side of the sewing machine and put on the spool.

Put the empty thread bobbin on the bobbin and wind the end of the thread a few times.

Hold the thread shuttle lightly with one hand, and pull the thread with your fingers to make the thread parallel to the thread shuttle.

Step on the foot pedal to rotate the spool, and slowly adjust the angle of the thread with your fingers to make the thread bobbin fully wound.

Remove the wound thread bobbin, rotate the bobbin and press it inward, and then load the thread bobbin.
