Sashing Decision

I was so "done" with my sampler quilt that I thought I'd just put it away and decide about the sashing later, but since it was still up on my design wall last night, I began to experiment.  The fabric I was sure was going to look great was a small olive green print, shown in the first picture.  Frankly, it just looked blah to me next to the blocks.

So I tried the other fabric that I had sufficient quantities of, and I really like this one.  The light fabric really makes the darker blocks float, and I think this will look great.  What do you think?

A funny thing happened with my cornerstones.  I originally thought I'd use a darker solid woven olive green print, but then thought this plum/brown would look better.  I had less than a quarter yard, and then one other small strip left over from the blocks.  I needed to cut 25 3-1/2" squares.  I was able to cut 24.  I searched frantically through my leftover yardage and my small scraps and did not find one single leftover piece of the print.  Wouldn't you know it?  As my mind raced to think if I had seen it in some online shop, I remembered I had a charm pack of the Cinnamon Stars fabrics and - YES - I had one 5" square of the print I needed.  Serendipity?  I think so!!!!
