I just bought a spool of Superior's Masterpiece thread and it is wonderful. However, I'm having a problem that I've never had with a thread before. When I'm done stitching a seam and cut the thread, the thread that remains on the machine curls up. Reminds me of curling ribbon or a pigs tail! I have to grab it and hold it staight out...and not let go!... before I start the next seam, otherwise it makes a thread nest under the fabric. I tried to wind it on the bobbin more loosely, but that didn't work. Besides, it is both the top and bottom thread that's curling. Does this happen to anyone else?
