I recently had to make the same decision...same fabric as one of yours, too. The red and white with small stars looks best against a clean white and dark blue. I even bought the the "Americana" red and blue stars against the muted off-white background (all at WalMart). In the end I used only the clear red, white and blue. I love the other and will use it to make a more "Americana" overall quilt for another veteran. Short answer: I suggest you don't mix looks.
