There is a Turning Twenty pattern called "Superman" that makes a 16" block and is good for large-scale prints. We have made two and posted them here. One thread was "Ralph's quilt"

http://www.quiltingboard.com/picture...t-t101268.html . We have two more that we're working on right now, but I have no idea when we'll get to finish them.
