try the soaking thing Tess, You might be surprised how it renews...not new, but flat and less cut upon looking. Could dress it with some endust? Try one and if it works, let her renew the other one?
Lucky you. I have one niece who when little stayed a week each summer. I managed to get one 6" cross stitch sewing project out of her, over about 4 years
I have it framed in my sewing room. She did love making those looped hot pads, as I did when little.
On the other hand she asked specifically if I'd hem her wedding dress and when she saw the trimmings asked if I could fashion something for her doggie who will be ring bearer. A lovely sassy scarf with an envelope pocket was produced
Lucky me!
