The American Quilt Story: The How-To and Heritage of a Craft Tradition by Susan Jenkins and Linda Seward has a few pages on the U.S. Sanitary Commission and Ladies' Aid Society quilts that you might find interesting. My daughter gave me The Civil War Diary Quilt by Rosemary Youngs which has some fascinating diary excerpts written by women during the war. Keep us posted on how your quilt comes out and have fun with the re-enactments!
