Thanks so much for your help. I have been playing with the machine today for a couple hours. I have Superior Thread 50 wt in the bobbin and top as well. The best I came up with so far is the top is not too bad, I think I can still see tiny dots, but the dots on the back is now gone. So I think I have to live with the tiny dots on the top. I am going to put in the same color and I dont think it will be too noticeable. I was also wondering if the needle may be showing a tiny hole and I think it is a dot. I am using the correct needle HLX5 - Size 14. Any other thoughts?
