From the spool up to the hanger directly overhead, over to the machine and through the TOP hole in the post that has two hole, over to the tension adjuster on top (the thing that looks like two stacked curved washer, twice around and over to the bobbin post beside the flywheel. Start the wrap around the bobbin clockwise looking at the bobbin from the top (bobbins have no real top/bottom, it's how you wind
them that determines orientation) and take through a hole in the top. Place the bobbin on the post being sure you maintained the correct orientation. Push the bobbin and post towards the flywheel and start running. It's best to disconnect the flywheel from the internal gears so that when winding bobbins the needle stays stationary.
