How frustrating for you!
It sounds like you got a very bad batch of thread.- can you contact the supplier (assuming you got this relatively recently) and let them know about the problem.
Do you have some other thread that you can "tug" to compare how easily it seems to break compared to the Aurifil.
I have quilts that are 20 years old that are "couch quilts" and not one speck of thread breakage - and that was using Coats and
Clark cotton covered polyester dual duty thread. Nor is there any "cutting" of the fabric threads from this thread. My quilting was mostly "in the ditch".
