This looks like a seam was sewn too close to the edge and pressure on the seam made the threads pull out. I have only seen this in the body of a quilt when edges were not matched up as a seam was sewn, usually by a pedal to the metal seamstress. Perhaps you can ease in some fullness by ripping out a few inches and easing in the fabric when you resew.
