I have heard of using newspapers as a "stabilizer" but the site you referred us to, says to not take the paper off, that it would act as a batting. My personal opinion is, that it's only 1 sheet of newspaper, so I don't know how that can break down with washing and be considered "batting". My other concern would be the ink, if you read a large sectioned newspaper, after reading, take a look at your hands, they'll be filthy from the ink. I might use newspaper as a stabilizer, but I would definitely remove the paper before I sandwich the quilt.
