I've purchased a few of their fabric (batik and print) and they are OK. Better than most of the fabric I've seen at Joanne's, but not quite as good as most of the fabric I've seen an LQS. I say "most" because there are always exceptions in both directions.
Their thread is another story. I bought I think 10 spools in different colors with the intention to use on a landscape quilt. I used a tiny bit of I think 3 colors and gave up and sold the whole lot here on QB. I HATED that thread. It says it's 50wt but when compared to a 50wt higher quality thread (like Aurifil or Superior to name only two) the CT thread was more than twice as thick. Also, the amount of thread lint was HORRIBLE. I was FMQ'ing little feet (just the outline of the foot!) and I did 4-5 feet that were only 4" long (so total thread used is perhaps a few yards tops??) and when I was done there was so much lint it covered the whole needle shaft about 1/2" all the way around. SERIOUSLY. I was even using a larger needle than I would have ordinarily used with a 50wt thread.
So from me ...
Fabric - thumbs up
Thread - thumbs down
