Warm and Natural makes several weights of battings. I used the denser one in my winter quilt, and a lighter weight one in my summer bed coverlet. I just like the way it quilts up, and my show quilts come out nice and flat but with good quilting definition. Quilter's Dream is the same, not just one option. I hate poly loft batting, it may look lightweight, but it is a b*tch to sew through and it is hot because it doesn't breathe the way cotton does.
