Thread looping underneath quilt
Your problem is the top thread. Make sure you lift the presser lever BEFORE you thread the machine. After threading the machine, just before you thread the needle, lower the presser foot, and test the top tension by pulling down on the thead. If there is little or no tension, adjust the top tension to a higher number, say from 3 to 5, or from 5 to 7, and test the tension again. If you fail to increase the tension by above procedure, look for cotton that might be stuck in the tension blades and remove it. Hope this will help you
