she noted that the thread is cotton covered polyester and i know polyester lasts forever (there are still some 70's leisure suits around) so maybe the thread has not been affected. i am currently quilting with thread from my clothes sewing days some 15+ years ago and it is fine, with no breakage or weakness. of course my thread was carefully stored away from the elements though.
good luck with finding the vendor though. i know some thread manufacturers have closed up shop in the united states and a lot of thread is imported in.
