About a year ago I purchased 3 quilt tops at $10 each from an estate sale. They were string pieced on a 1960 Oklahoma Stockman magazine (most pages similar to newsprint). It was fun to look at the articles and ads on the paper. I loaned one to the quilt display put on by the Ranching Heritage Museum at Texas Tech last summer. I subsequently sold 2 of them and am now harvesting fabric from the last one to be used in a vintage quilt I am making.
I am in agreement that the paper should be removed if the quilt top is to be finished.
