I call it "Warm and Naturally stiff as a board." Not only does it get stiff if you quilt it very close but it is so flat it doesn't give your quilting any definition at all. I use Quilter's Dream Select, Quilter's Dream poly or Hobb's Heirloom 80/20.
Try lots of different battings to find the ones you like for the look you want in your quilts.
