Making curtains for my stepsons room and I'm just sewing along hemming the curtains and all of a sudden my machine makes this horrible noise! Looking all over trying to figure out what just happened. Needle good, just changed that, bobbin good, plenty of thread. Where the heck did the top thread go? Oh my Lord, actually ran out of thread on the spool!!!! I don't ever remembering that actually happening before!! Of course, didn't have anymore of that color, off to JoAnn's to get another spool. Gave up for the night and will restart today!!!
