At my step-daughter's wedding this summer the guests signed a book, they etched their names in a silver tray and they signed muslin strips for a wall-hanging I would make her. I also put a plastic pocket on the quilt to stick a picture in of her and her hubby - the picture quality is better that way. I haven't quilted the quilt yet so all the ribbons aren't on yet (have to hand sew them on after the quilting), but here is a picture of the wall-hanging. Their reception had a huge candy table, so that's where the idea for the quilt pattern came from.
