I don't know the pattern but it is lovely. I'd try to hand quilt it. Those green areas would be wonderful to show off some hand quilting. I showed the photos to my DH (who happens to be an archivist at a local historical museum) and he suspects based on the photos that it was made sometime in the 1930s or 40s. He suspects that the prints are flour sacks (he says if the weave is really tight that they probably are).
Of course, you're always welcome to send it to me if you can't think of what to do with it. LOL. Congrats on your great find.
