Okay, I have been doing since I started batting like this since I started 9 years ago. I get 5 white washing hand squares wet with cold water. I put the batting ready with sprayer water lightly gently in the dryer. And then I throw in the squares every time 5 minutes to fluff it up and it does gets most of the batting the wrinkles out. They lose lots of gentle creases when it is done. When I started drying it and when they are done - love them with the top of the backing and then the top of the batting and then the quilt. They get it done.
