All great ideas and beautiful embroidery!
I have taken the hand-embroidery and crocheted edges of tablecloths and the eyelet-type work and used it in valences for draperies. For example a white-on-white linen hand embroidered table cloth I cut into 4 triangles, gathered each triangle over a red-white-candy-stripe under-valence and tied with a red satin ribbon in the center...etc. Wasn't a quilter then! Unfortunately there was 'water penetration' and the antique tablecloth got huge brown stains.
Better to use these antiques where they are unlikely to get trashed.
