Some time ago I e-mailed C&C and asked why we can't find the cotton wrapped polyester thread anymore. Every spool I pick up is 100% polyester. Reply was to be more specific. I asked again in reply to their reply. Never heard back from them. I don't purchase their product anymore because I don't like straight poly thread. I'm still using the supply I have for quilting and sewing. That's my experience with them.
