My cousin gave (yes GAVE) me a quilt top that she inherited from her sister. We know nothing about it, but I took it with me to my quilt guild meeting on Tuesday and the woman who was presenting the program that night is an expert on antique quilts/fabrics. She looked at my quilt top and said that one of the fabrics in it was a "centennial" fabric from 1876. She guessed that it was made somewhere between 1876 and 1900. I am just thrilled. I asked her about leaving it "as is" or quilting it. She said go ahead and hand quilt it, but use a very thin batting, hence my original question. What batting should I use?
