Terri, I hope you don't mind that I tried a little copy and paste of your quilt in Windows Paint to see what it would look like with a dark blue or a light inner border and the fabric you have there. I don't know which I'd like better, but maybe this will help you to decide what you'd like to do. It seems to me that either one would look great. For the inner border I used the"eyedropper" tool to pick up colors that are in your fabrics. The piecing you have done there is wonderful! I have to admit I didn't think that border fabric would work at all until I saw it like this, with an inner border to help it relate to the rest of the quilt.
