P.S. I don't want to be a "THREAD SNOB" either, so I have tried Superior & Aurifil. Love them both. A little pricy, but I guess I'll have to invest so no more broken threads & ruined quilts. Never used Serger threads for quilting, no matter how tempting it is.
*** 2 more questions for you all experienced quilters?***
To prewash or not prewash quilting fabric, if not prewashed, could that be why threads are breaking?
