Well, my first impression of your fabrics is that they are pretty but unexciting, pattern-wise. The bold pattern of the peace sign fabric might be a little overwhelming in the border as it doesn't have anything to play off of.
Perhaps something pretty simple and easy like a D9P with sashing in maybe a white tone on tone. Sew each 9-patch with a narrow sashing, relative size would depend on the finished size of each block ( 1-2 inches? ). Then make your cuts (the disappearing part) , sew them back together, and then just sew the blocks together. Or you could even sash between the finished blocks too if you want. You can preview that and see if you need it.
I've seen some pretty plain D9P blocks totally brought to awesomeness by using stripes, large dots, or geometric patterns in the sashing.
Good luck, and please show us what you decide to do!
