I posted the link to the fabric manufacture Connecting Threads uses some time ago. It was a very impressive plant. Not third world or slave conditions. It is a plant known for it's quality and manufacturers for brand name clients. I'll see if I can find the link again. The thread is made at another plant, there are only so many plants that make thread no matter where they are. It's the client that specifies the quality of the thread, not the plant. It's easy to research on line where any fabric or thread is made.
