It makes a definite color statement, and it does pick up a few of the blues in the star blocks. I agree with a few others, however, that 'revisiting' it later, then deciding how you feel / what you want to do is a good idea.
I also agree that a solid border would allow the focus to be on the beautiful blocks you've made...perhaps a mid-value gray that's between the color of the star points and the sashing color.
It's a beautiful quilt that would be perfect in a light blue or gray room as it is. But I do think it would be awesome with another border, either replacing the blue floral or adding to it.
Thanks for sharing. The blocks are totally impressive.
