There is a variation of rail fence that might possible make your fabrics show off how pretty they are. I have seen it on our Quilting Board before, but I don't know what it is called. I made one years ago, using only two fabrics. One I wanted to show off and then white.
This may not be at all what you are thinking of...but if I can find a picture of my quilt....and you want to make a quilt using your great fabric, it might work for you. Instead of using one fabric, you could use all four of yours and scatter them around. It really is a rail fence type block, with the center part being wider than the outer two, and then the blocks are alternated. I was trying to make the airplanes look like they were flying in the clouds...though it didn't turn out looking that way.
