Thanks so much everyone. I did what you said QuiltnNan and sure enough there was some thread caught below the bobbin case. I was only to get it out with the little brush and then pulling with a tweezers. Amazing how I had missed it after going over it with the brush several times. My quilting is working again. Oh my this machine is so touchy. Thanks again for your quick responses I greatly appreciate it. This board is truly the best.
