Like all household sewing machines Singer is this what the famous break of threads also a sensitive piece. Negative I would like to evaluate the absolute hidden presser foot and the minimum height of the raised presser foot. What does it mean you have a substance that is slightly thicker at the beginning, one hardly gets the underneath, let that transport handled immediately. So more sorrow than joy when sewing. I advise against it, if the manufacturer is not geared to better equipment.
