I have not used that many different battings...I just used a Fairfield 80/20 for the first time a bit back for something. I can't even think what. I can see liking it if I had a long arm, but I got the quilt started, then something happened that it set for a while puddled under my machine and I swear it seemed to get fluffier. Still, I did like it after it was done.
I have used Warm and Natural and Warm and white, and like both. A lot.
So far, though, my love is Quilter's Dream Cotton. Something about the way it softly drapes...even after quite a bit of quilting.
