That's a good question. I have seen some quilts where the micro quilting makes it almost cardboard thin and about as stiff. Others where there is so little quilting, I wonder if it will hold together in the wash. I usually use a 80 20 batting. I have a tendency to do a meander about as big as a 3" puzzle piece. But then I am definitely a piecer not a quilter. Once a top is done, I quickly finish so I can start on another.
