Okay, here's what I came up with. I took fabric A and the piece from E&F that contrasted the most with A, constructed nine-patches with those two fabrics with the E/F fabric in the center and on the outside corners. Then I took fabric C (which is supposed to be the darker fabric) and made nine-patches with the other fabric from E/F, with the E/F fabric in the center.
Don't worry about having enough fabric. I had plenty and had even cut some blocks wrong.
You will be cutting 12 2-1/2" pieces from the longer strip combo and 6 2-1/2" pieces from the shorter one.
Here's what finished 9-patches look like. I decided to change my red fabric out as it didn't have enough pizzazz.
