Using the materials you have displayed, I would do three borders. First, a narrow dark blue, second, an even narrower orange, and third - either dark blue again (and bind in either orange or dark blue) - or the lighter colored fabric in your quilt, bound with the dark blue. I LOVE the cream colored fabric with the orange and blue in it, but I think the design doesn't compliment the other fabrics in the quilt. I would, however, consider using it as my backing.
