Thanks for your reply Barbara. The factory sent me back a new machine because mine was defective. I tried using a 80/12 metallic needle and am having better luck this time. Every time I use the scissor feature, I have to rethread the machine, remove the bobbin and put it back in. If I do not do this, It will not sew right. The back is full of loops in I do not rethread the machine. I just saw the video on changing the tension so I will also try that. This machine is 3 times what I paid for my last pfaff and does not free motion nearly as nicely as my first pfaff. Barbara, do you do a lot of free motion quilting on your machine?
