Somebody has mentioned that Elmer's School Glue is not really glue but starch and that's why it washes out of our quilts that nicely. I do not know if that is true or not, but I have a gallon of Elmers and I use it for many things besides my kids crafts and quilting. Did you know that you can use it instead of cracknel compound to make cracled finish on furniture? I did on two tables and they turned out great.
