I do not know if this help you might want to try and Inspra needle - I hear it is sharp and has a groove for the thread and if you have alot of dust bunnies in your bobbin compartment it is the surface of the thread that produces those dust bunnies - I have not tryed this needles but just ordered them Friday to try on my mega quilter.... And I will see what happens - My thread does that every once in a while and thought It was the thread which is the star thread and because I want to try other threads - I thought I would try these needles.....
