Does anyone know what kind of PUL bum genius uses for their diaper outers?  I have felt them and they feel so much more gentle and less abrasive on delicate skin, than the PUL I got from hancock fabrics.  Just wondering what they use.  Also, what makes one PUL fabric softer and more suede-like on the outside? Is it just the difference between 1 mil. as opposed to 2 mil? I'd sure appreciate anyone's help!  Thanks, ~Naomi
