I would fussy cut squares from the large print, then border them with a green or pink fabric that reads solid. I'd use one of the geometrics for sashing and the other for the backing. One thing I would do, is fussy cut the geometric used for the sashing, making sure that I kept the pattern straight rather than just cutting length-wise or width-wise strips. The print is so strong on both the geometrics, it may be distracting if they are cut off pattern.
