With the fluctuation in the price of cotton goods and the base cloth being produced, this is an impossible question to answer. You just have to learn to feel the fabric and learn what is better and not so good. There have been a lot of posts about this question. And to, it is not always the most expensive fabric that is the better and you can get good quality at chain stores and lesser quality at local quilt shops.
Having said all that, look at the major brands as a starting point in your education about fabric quality. They try to have the best fabric quality.
I am sure someone here will point you to other posts on the subject. I never have success in searching.
