My last quilt was backed with tea stained muslin, to me it was very boring....I do prefer a print coordinating with the front. I do love to piece my backs, that wasy they are all but reversible, and you get two for one. Current throw quilt I am working on has well over a dozen calico prints, with all my left over fabric, will cut squares, don't know what size yet and make the back. My inner brain (?) says it will be cut, will see.
