I am making a quilt for my niece who is having a baby in January. I am only using fabric that I inherited from my mom who passed away this spring. I want the baby to have something from Great Grandma, I am to the point of choosing the backing and found the perfect backing in her stash, however it is three long strips of pastel Minke fabric. I have never sewn with it before, but have seen it used as a backing. Would sewing them together with my surger be best, is there something I should know about the knap or stretch? What about quilting it?
