I found the above online. It gives some information on resale of licensed fabrics (items made from them). You can't sell a quilt or clothing item from a commercial pattern without permission.
You do have a right to make an article/quilt of your own design (or one in public domain...ie, 9 patch, Irish Chain) from licensed fabric...the article references a lawsuit that a company won against Precious Moments. They actually had to change their labels to say the pictures were the copyright of Precious Moments, but they were allowed to continue to make and sell the articles.
For more information, check the link above. I had read this article before (and the linked articles in them)...and when I used design logos, I still checked with the schools to get permission....it's only common courtesy to do so.
