Just wanted to bump this. Saw the thread and DID NOT read it but it stuck in my head.
Going to get my quilt from LAQ tomorrow and MUST have it all done by April 13th. Needless to say, my machine was running great this afternoon. Not so after dinner. Nearly had a fit! Thanks to this title for floating through my mind as I was trying to solve the problem.
Lint was the problem and now my machine is running beautifully again. Thanks
