pfaff grand quilter 1200 thread fraying and skipping stitches
We have a pfaff grand quilter 1200 and like other posts we have started having problems with the thread fraying and skipping. we have done everything suggested by others have this problem, but no luck. one thing we did notice in cleaning the frame (new generation Grace), carriage and rollers, was that the plastic rails that the carriage rides is cracked in several place. Could this be the case of our problems?
