This is the back of my Nine Patch One Patch quilt. Two width of fabrics were just four inches short of what I needed for the length of my quilt. I didn't want to cut more backing fabric. There is a drawer in my storage system for "quilt blocks". I found the half square triangles and four-patches in there. I didn't have enough of either for all the way across the back, so I used some of each. This added just the width I needed. Amen.
