My instructor has recommended preparing a sanded surface myself when I complained of the difficulty of finding sanded pastel papers, but he is primarily an oil painter, and offered no instructions. What paper/board, what substance should I use to get the sanded texture?
I love Wallis paper but it's so expensive and I don't really care for the Canson papers much. I'd love to experiment with my own grounds but don't know where to start. Any one have any suggestions?
