Terraskin is about 3/4 mineral powder to 1/4 non-toxic resin combined to make a paper similar to Yupo which is 100% polypropylene. I have used inks, watercolours, thinned acrylics and coloured pencils on both. The Terraskin is slightly more textured than the very slippery Yupo but I enjoy using both. Watercolour sits on top and takes days to dry in puddles which can be effective. Absorbing the paint with a paper towel leaves
interesting shapes as well. There are many excellent images and comparisons online.
