Is the eye of the needle large enough for the thread?

Is your bobbin area clean?
Is the thread getting caught on the spool?
You are positive the machine is threaded correctly?
If everything else seems fine, adjust your upper tension.
It's a brand new schmetz needle but I can try the one from my old machine which I KNOW is fine. I just whizzed my little brush round the bobbin and feed dogs - I always do that aftter quilting to get rid of the fuzz. Nope, the thread is sitting fine on the spool; and I checked my threading and am positive it's done right; could the tension discs be faulty? I tried reducing the tension to 2 which is way low and it STILL did it!
