I've been having a problem with my thread breaking constantly during FMQ (every few inches). After replacing my needle, adjusting the tension, and cleaning the bobbin case, I decided to try a different thread. I used a trilobal polyester by Signature A&E Inc, and it didn't break!
This is primarily an embroidery thread, but its also the third brand I've used and the only one that didn't cause problems so far. Are there any issues with using this type of thread to quilt?
