Holly Molly! I have a quilt that is at least 40 years old. Backing, Sashing and borders were cotton poly blend and are like new, cotton is worn off a lot, faded with some holes showing and the batting is almost nonexistent. I did not take the quilt apart but I can tell by simply touching it. It was quilted by hand pretty sparingly who is probably why the batting is almost gone. Maybe that was the problem with your quilt as well. If not that than it must be the batch you used was not as good as it usually is.
