Sometimes I have seen fabrics with word on them used as a background fabric if the other fabrics are bright enough. I also see Lori Holt (quilt designer) use a lot of fabrics with words on them. You might want to go to her website and look around at her blocks and see how she uses fabrics with words or some kind of writing on them. Her blog is Bee in my Bonnet. I have a couple of her books and use them all the time for ideas.
