I picked up a pad of Stone Paper at Walgreens on the weekend. It is a smooth surfaced paper made from stone instead of wood pulp. After outlining the face with a Faber-Castell Pitt pen, I decided to experiment with my Copic markers. They look like watercolor on the stone paper. I was able to use my fingers to manipulate and mix the colors. I mixed a little white acrylic on the face to add highlights. I want to play with the paper a little more before I buy a pad without lines online. They are a lot more expensive than the $3.99 I paid for the lined pad at Walgreens.
