I just found an alternative way for smaller quilts; take 2 squares; maybe 5" and fold on the diagonal and press; put one in each of the top corners with the fold towards the center of the quilt and stitch the two raw edges down even with the quilt corners; then put a rod under the two flaps of the corner triangles. I was thinking just before I wrote this that if it is a wider quilt you could make a tab and place it in the center or evenly spaced between the corners and put the rod through it then under the corners; you would probably have to tack the bottom of the tab down to the back of the quilt but would eliminate fabric all the way across the top of the quilt.
