There is a pattern that I've used with large scale fabrics that really works well. It's called "Just Can't Cut It."
You would use your Pirate Fabric plus five other fabrics. I think the largest print would be cut into 5.5" squares, but I'm not positive about the measurement. I know that some clever person can provide you a link with where to buy this pattern. I've seen it in 6 local stores over the years.
It's an easy pattern for a lap size quilt that really goes together quickly.
