Joesmom and Kalama, I understand about the dismemberment issues. My own thing is "no dead fish" any time I use fish fabric there is a direction and no fish float....
Just as a caution, One Block Wonder type with animal fabrics almost always have this issue with rear ends. I have a friend who embraced the concept and made two quilts from horse fabric, one of which had the horse faces for a granddaughter I think, and the other made of the other ends for her husband as a couch blanket. He appreciated the joke, but not everyone would!
