Ann Marie, you are so lucky to have such a wonderful quilt piece and that gorgeous wedding dress. Have you visited any on-line quilt shops that specialize in the Civil War era fabrics to see if they have any reproductions similiar to the prints in your quilt piece? A shadow box would be a great idea along with a short history of where & how you found the piece attached to the back or side of the box, depending on how deep you make it. Does anyone in your family have old photograph albums that might have a picture of the piece of furniture the quilt was found in, or of the person who made the furniture that you could make a copy from to place in the box (as long as you hung it away from direct light) & please don't cover up any of the fabric since it is of historical value to fabric historians. You're a very lucky lady to have 2 such special pieces of family history.
