They both work well. For tension control, the Jamie Wallen method has helped me a lot.
Quilttiger, I just had an ah ha moment. I just put Magna Glide Delights in my bobbin yesterday to see if it made a difference. I have Magna Glide thread in the top and thought that maybe it would help but it got worse. I did not know that I needed to remove the anti backlash spring. I went to the sight and sure enough.....on my way down to my sewing room to work on it, yet again! I also just watched Jamie Wallen......thanks!!! I have renewed hope.
