I can see them appliquéd onto a crazy quilt blocks and go from there by embellishing all of the seams in each heart with ribbons and lace and beads since they already seem to be crazy quilted together. Pretty stitches to hold them on or sew them onto a block and cover the edges with old lace or crocheted lace. That way they would not have to be laundered like a regularly used quilt since they look delecate with age already, and it would really show them off as a pretty wall hanging. They really are beautiful with age and appear so soft.
