No! I am not an expert on battings, but I really don't know why your quilter friend said you should never use poly. I have used poly in a quilt, and I have used warm and natural cotton batting. In my experience, the poly batting is loftier and lighter in weight. Maybe other members will weigh in on your question. I think the poly batting will work just fine and good for you for finding a bargain.
