I love their thread and when they have a sale I stock up bigtime! I love having a thread stash to rival my fabric stash, and their prices are amazing.
I still use thinner thread (Presencia) for piecing and when I'm doing SITD quilting, but for topstitching or free motion quilting or ANY sort of decorative sewing, CT is my go-to thread.
I do think CT is a little lintier than a "premium" thread, but to me that's a pretty minor thing. I de-lint my machine all the time anyway. For the price, I can stand to brush out the bobbin case a bit more often!
