I have completed the center portion of the wall quilt for my DGS but I wasn't able to locate the coordinating print fabric that the designer used for the border. I am thinking about using the darker blue for the final 5" border using cornerstones. But what to use as cornerstones? I thought about reducing the airplanes and appliquéing those but that would take away from the center part of the quilt IMHO. Or use a bit larger pinwheels. Or would just plain no print fabric be better? Or no cornerstones used at all? Suggestions would be so appreciated. Would love to get this done. Thanks.
