I, too, was recently informed of the right and wrong side of batting. I've made many quilts using warm and natural. Only one of them has white dots on the back. Unfortunately it has midnight blue fabric, so I could and still can tell. Apparently you and I have been lucky in the past. Your quilt will still look stunning, no matter if the back has issues or not. It will still keep someone warm. If you've already started it, then only you can decide if it will be worth it to un-do it or continue on. Good luck with your quilt.
