Dealing with Upper Thread Breaking - Sewing - as part of the expert series by GeoBeats. Usually when the upper thread breaks, you have got a couple of things going on. The thread could be caught on the spindle on the back of the machine. So, when your upper thread keeps breaking, make sure that it is not caught on the spool itself, or make sure that it is not wrapped around the bottom of the spindle. Either one of those things are going to stretch your thread, and then as soon as it resists, your thread goes. The other thing you want to double-check is that your thread is actually in place. So, you want to make sure that all of the channels the thread is supposed to go through are actually intact. Thread is going to break, or upper thread is going to break because it is getting caught against something. Rarely is it a problem with the needle or what is going on under the presser foot.
