I agree with Linda M. I would do more quilting on it. I have always used cotton or poly batting's and have never had a problem. I always throw my cotton batting in the dryer to remove the wrinkles before using it and I always prewash my fabric and that's how I get a nice old look to my quilts after I wash them but I never prewash the batting. I don't think I'm brave enough to use wool because you never know who's going to be allergic to it.
