Could you add a pieced strip between your corner border block and your first border block? You would only need to do it on the horizontal borders. Piece a strip with your pink in the middle and the background fabric top and bottom. It would be like Gay’s example, but ivory/pink/ivory instead of your single dark color. It will extend the design a bit, but if it’s very thin it might not be noticeable.
