At the Sisters Outdoor Quilt Show, many years ago, there was a wonderful display of quilts made from wedding gowns. (These quilts were on the walls of the clock store, not outdoors.) It seems that your wedding dress means more to you than to your daughter, so perhaps you could make a quilt from it and use leftovers for something smaller for your daughter. You can display and enjoy the quilt, your daughter will have something from it for the wedding, and you may find that she will become more sentimental as she gets older.
