Can I Use A Sheet As A Quilt Backing?

Are there less expensive options for quilt backings that we don't know about or are dismissing? I have been using flat sheets for quilt backings and I am hooked!

I would love to hear your opinion! Should we only use expesnsive, high thread count fabric or is there a time and place for inexpensive fabrics such as muslin backings and old sheets?
