I have used Minky on many, many quilts over the years- even queen sized ones. It is a favorite backing. I pretty much always meander quilt it- turns out wonderful. I always use batting, I like the extra loft plus it keeps the seams from the pieced tops from being felt on the back. The key is to Smooth it- not stretch it as you go.
