If it were mine, I would definitely accentuate the floral print either by adding two sets of triangles around the original square (using the coordinating fabric) or add strips of the coordinating fabric to a square. I don't usually use a pattern but make up my own layouts when I see a certain fabric.
When I add triangles to all four sides of a square, I take the original square (whatever the size) and add one inch to the measurement of that square to cut a square from the coordinating fabric. I then take the square from the coordinating fabric and cut it corner to corner, thus giving me 4 triangles to add to the original square. After sewing the 1st set of triangles to the square, I would do the same process to get 4 triangles from the second coordinating fabric. Don't know if I am explaining it correctly. Sometimes I know what I mean to say but putting it into words is another story. I would then add a coordinating pink sashing between the squares I have created. Good luck.
