I wasn't sure if you wanted just backings or backgrounds, but here in a recently pieced BOM that I used muslin for the background. I didn't have enough beige regular fabric for the whole project, so I used some muslin that I bought as Joanns by the bolt. I liked how it all sewed together, and I am stippling (for the first time ) all the background. It is taking much longer than I anticipated so it has become a filler of time quilt
