I have had a flower stitch attachment for three years and it works just fine for what it is designed for. I have both Singer machines (40+ yrs old) and two Viking Designers. I worked in a Viking dealership for two years and noticed that most machine "malfunctions", no matter what brand, were due to operator malfunction. Time to get out your machine manual and start from page one. You could have something confused. Did you remember to drop the pressure foot? Also check stitch width, stitch length, speed, tension. All can affect the process negatively. Good luck.
