I'm late to the game, but something like this would showcase the fabrics, while having a slightly more interesting pattern than just blocks with sashing. You could use black for the diamonds between the squares. The fabrics are so beautiful that it will look great either way, though!
Directions available here. I just made a quilt of these snowball blocks, and it was SO easy.
