I am planning a B9P for my bed one of these days. I'm collecting the fabrics slowly. Generally I make mostly scrappy quilts, and I think for a scrappy B9P, rather than focus on having one pattern for each section, I would focus on using one color, in scrappy prints. It might not have quite the same look, but it would be a fun way to try one.

For example, pink florals then picking up a color from the pink floral, perhaps yellow, then make that row yellow florals, then to a color from the yellows, perhaps blue, and doing blue florals... just an idea.
