When I see posts like this I think, "Oh NO, someone ran into a self-appointed quilt sheriff." Personally I don't believe that our quilting ancestors worried about what brand or style they used, they were just happy if they found enough stuff of some kind to finish a quilt. If you're lucky enough to see some of those quilts they're beautiful. Use what you have and don't worry about it. Quilting is to enjoyed so don't sweat the small stuff. Use the best things you can afford and improvise the rest.
