I made a rag quilt for my niece for Christmas and I really wanted to use minkee since it is dang soft. I would use it. But I wouldn't use it for just the back. I would add some pieces on the top and have some pieces on the bottom. Spread them out so you don't get a top and a bottom with minkee. They do not rag at all but they do feel and look nice. I used flannel and cotton as well with it. And I went ahead and added batting to everything. Even the pieces with the minkee.
