Applique cups and saucers (different sizes) and tea pots made of the embroidered remnants or if the embroidered bits are too small, use them as decorative motifs on the dishes. If you use white, or lights for the china, each dish or set of dishes could be featured on a different (floral) background. If she has saved crochet work, doilies would be fun under the saucers or on their own.........
