If it has a spool cap, place that on top of the thread to hold it in place. If your machine’s spool pin is on top of the machine, it may not have a spool cap.
If your bobbin has more than one hole in it, you can use any of the holes.
You may want to start by pushing your pedal slowly to find your rhythm, but there’s no reason to wind your bobbin at a slow speed. If your bobbin fills unevenly, you have likely wound your thread around the tension disk in the wrong spot. Check your placement of the thread. If you believe you have done it correctly, then wrap it a second time to ensure that your thread is winding evenly. If your thread catches on the notch of the spool, try turning the spool over and working in the opposite direction of that notch.
Your bobbin is full when you reach the edges of the sides of the bobbin, making your thread flush with the outside edge. If you keep loading your bobbin past the sides, then the thread will slide off and unwind.
