I agree with an earlier poster who suggested adjusting your bobbin tension.
I agree but definitely. I use bottom line on everything from piecing to quilting. I use it on a Brother and a TOL Bernina. I find it works wonderfully. When I use it for quilting I use So fine for the top thread, but I have used it effectively with 12wt jeans thread on art quilts as well. I don't mess with the tension much and then only with the top tension. When quilting I lower the tension and lengthen the stitch but that is about it. Bottom seam problems are usually top tension problems or bobbin
threading problems. I iron often in the piecing process and never have had a melt down issue with bottom line, however with another brand there was some. I suggest you email Bob at superior threads with your problem, he is very helpful. I can heartily recommend, also, so fine for use with bottom line.
