Hello Adeline,
I can't remember if you have a bobbin case or if the bobbin drops flat on the top, if it drops flat on the top the bobbin should turn anti clockwise, if you have a seperate bobbin case the open part of the bobbin case should face you with the finger to the top, bobbin in so it turns anti clockwise, thread through the spring and pulled to the back of the bobbin case, take the latch on the bobbin case to stop the bobbin falling out and inser the bobbin case into the raceway, if you need a manual I can attach a list of sites if you email me below.
