This is hard for me to answer, it all depends on the quilt I am making. I like the Warm and Natural for my Vintage look quilts because it has a shrinkage like nobodies business! :lol: :lol: (I never prewash anything)
The quilt that I made for our bedroom I am using a high loft poly fiber batting because my wife loves the "Comforter" look. And babies quilts I use the Poly fiber but low loft.
I guess its what ever the effect I am going for....
