At our fabric store, we categorize cotton and cotton blends in a couple categories. In addition to particular brand names (ex.a designer's name) and particular fabrics (such as a batik), we separate them by calicos (ex.quilters type print, small design, all over pattern) and novelty. We define novelty as 'things' - animals, toys, food, space, landscapes, buildings, money, vehicles,etc. We tell a customer that if you can name an item, then the fabric is probably in the novelty section. Hope this helps.
