ive made many quilts with minky backing- I do use batting- but I live in a cold climate where we want our quilts cozy/warm - it's a personal choice- what ever you want. it is pretty difficult to bring minky from back to front for binding- you might want to do the *pillow case/birthing* method if you do not want to attach a regular binding (if using batting lay down batting put top right side up ontop of batting, put minky right side down *facing the top*; *just put top & backing rightsides together if not using batting) stitch all the way around- leaving an opening for turning right side out- turn right side out- poking out corners (I use a chopstick or crochet hook for that) close opening and quilt as desired.
