I'm not Nonnie, but I can tell you that Harriet Hargrave is the person who developed the first 80/20 on the market for Hobbs in an effort to add some polyester to make the cotton batting easier to needle for hand quilters.
It is my favorite batting for everyday quilts, but there are lots of battings on the market, so you should try different ones to see what works for you.
For something that I want to have more dimension showing, I use Hobb's wool batting, either by itself or layered with the 80/20.
