it depends on the quilt, if it is for someone here in northern michigan i put batting in and back with fleece, if it is for one of the kids in florida i do not bother with the batting, they love the fleece back because of it's warm coziness but do not need the extra weight of the batt. i used curly minkee on the back of my mariner's compass quilt...it is so wonderful! the grandkids call it the 'get-naked' blanket!
