Is it already quilted? Washing just the top can cause this to happen, no matter how careful with seam allowances you are.
Not seeing the quilt...my first thought is 1/4" or 1/2" ribbon...Use Steam a seam (it's got a slight sticky on it, so sticks to the ribbon and quilt before you press it with the iron. ...once you have all the seams covered (I would use long strips of ribbon, and just crosshatch them following the seams) and ironed down.. stitch down both edges of the ribbon to secure it. You could also use flat lace, and even just the decorative stitches on your machine...honeycomb stitch, etc.
