You will get mixed reviews on CT threads. We use it for piecing and for quilting - as a matter of fact, it's all we use. We have several of the colors for quilting, but mostly use the "Natural" to piece. It creates a lot of lint, but we clean at every bobbin change, so it is not a problem for us. Some don't like the lint, and some have said they get "blobs" in the thread. I've never had a "blob," at least not one that caused any problem with my machine. I love the color selection, the amount you get on a spool, and the price. And, if you order $50, shipping is free. I would recommend you order a couple of spools and give it a try.
