When I taught sewing in middle school I always told the kids to: HOLD THE NEEDLE THREAD IN LEFT HAND--TURN HAND WHEEL 1 COMPLETE TURN ONLY WITH RIGHT HAND AND PULL UP ON THE THREAD IN THE LEFT HAND. A LOOP SHOULD COME UP (THE BOBBIN THREAD) PULL THREAD THROUGH AND YOU ARE READY TO GO.
Good luck. Hope this helps.
