I have the same tension problem on my long arm. I'm not quilting much because it is so frustrating. I have turned the top tension knob so much, who knows where it is actually suppose to be. I've also turned the bobbin tension, which I hate to do. I think I'll never get it to where it's suppose to be. Wish there were pictures somewhere that tell us how to adjust for each problem. Like eye lashes on the back, adjust the top tension... which way.... If you have heavier fabric, like flannel, how do you adjust the tension. You would want less tension, right because your fabric sandwich is thicker???
