I have tried watercolor pencils with an Aquapainter and also watercolor pencils and a blender pen on white cardstock from Wal-Mart. I believe Hammermill was the brand name.
Nice weight of cardstock.
Failure with watercoloring every time.
I believe SU cardstock (at least the lighter neutral hues) has a surface sizing that stablizes the waterproof inks.
I have worked with other brands of cardstock, some more expensive and some less expensive than SU cardstock, and prefer SU hands down for price, quality and my overall satistfaction.
