jjs56, That is one spectacular quilt! I realize that is a side comment to the question in the thread. I have never seen a quilt quite like that, but, it is just beautiful. It is very traditional and contemporary all at the same time. But the muslin question. There are lots of different qualities of muslin available for purchase and each has specific uses. Good quality muslin (high thread count) are perfect for using in quilts and for backing. Lesser quality muslin has lots of uses in the sewing areas. I keep a variety of qualities of muslin in my sewing room and use them as needed.
