The bobbin area has a door that latches. Finger is on the latch. The bobbin goes in the bobbin case and thread goes through then that whole thing just sets there then close the latch. I'm sure there is more to this... I don't have a manual. The bobbin thread makes magnificent loops - wow... probably how chenille bed spreads got invented or something... another pic of the bobbin case.[ATTACH=CONFIG]373745[/ATTACH]
