Not sure that any of the single layers of batting will give you the result you want. A recommendation in a blog I read was to use an Army blanket instead of batting. If that is not an option, you can put two layers of batting together but that will result in a somewhat thick sandwich to handle while quilting. Some quilters use a layer of cotton (like Hobbs 80/20 or Warm&Natural and then put a split layer of wool batting over top of that. (they carefully separate the wool batting into two thinner sheets.)
