I would do De novo from Benatarex fabrics. Free download. Use the larger floral for the bigger block. You would need to add in several other fabrics pulled from the big floral print (pink, green, yellow, even brown in a textured, solid type of fabric). Black sashing.
Here is the link.

Here are some pics from my "Quilt Ideas" folder. I think that I got the pictures from the QB, because this is where I get my best ideas. I don't know who the maker is, so if it's your quilt, please let us know. They were so beautiful, I kept them for inspiration.
