Well thank you all for your help and suggestions. Unfortunately, I tried all of the above with no success. This happened 2 weeks ago and I thought it was just a bum spool of thread, but this is another spool of thread. Can it be something I am doing wrong with my FMqing? Keep the suggestions coming and when I figure it out I will let you all know. I usually really enjoy FMQ and never got nesting or loops before.
