The thread may have become tangled as a
result of incorrect upper threading. Make
sure that the machine is correctly threaded.

Incorrect sewing may be the result of
incorrect upper threading or sewing thin
fabrics. If there are poor results from the trial
sewing, check the upper threading or the
type of fabric being used.
