As stated a metallic needle makes all the difference. The second is how the thread is coming off the spool. If its a cone use a cone holder...Note if its a short cone .. elevate it so it does not wrap around the spindle .. I use another spool of thread under the short cone. The third is your tension.. many times I have to loosen the tension with metallic thread. I too have found using embroidery thread to be easier to free motion quilt.
