Hi Rhonda I'm using a korbond thread. I don't know if that's a good make or not? I am using the needles that come with the machine and I had checked what way the bobbin thread goes online and manual. I use the bobbin winder to wind the thread on to the spool. I think it's all wound correctly as far as I know? But I will check that it's in the tension discs properly in a minute, just made me think, I think I threaded it all properly but I will check x
