The Fat Lady hasn't Sung Yet

As FiberObsession commented on my last post, I just wasn't going to be content until I did something to the Dresden centers.  I chose this rose/red fabric because it was THE perfect center fabric.  And until I dreamed "what if I put a center button and smaller dot" like I was doing on the corners, I thought this 102" quilt was nearly finished.  That's me...the consummate dreamer.  If it would just end at a dream, life would be easier, or at least faster :-)  It's the constant dreaming that makes me a creative quilter.  It tests limits and boundaries, and constantly pushes me to consider new and different things.  Not entirely bad.  Afterall, there's not really a deadline for this quilt.  

So, I tested a bunch of the green fabrics for the central buttons.  I have decided upon the deep check (2nd picture) for at least half of the larger buttons.  I think I have another dark green print I will use for the others.  

I have the circles just staged, and not yet stitched.  I think that the deep cranberry centers will be a little larger than what is shown.  So what are your thoughts?...Am I nuts, or is this a positive alteration to the design?  Is the green the right color? So many questions and doubts.  Guess time will tell...
