Love the fabric. Ideas - You could cut each picture out along the frame line, then cut the frame to 1/4". Then reframe the pic. with fabric of choice, To make blocks the size you want, either round-robin style, or mix small with large using your background fabric (the bron maybe)) as a spacer. Tie dye for border. The daisies would make a nice backing.
Regardless of what you choose, it will be beautiful.
