I pulled out a piece of Yupo last night and this is what happened. I love working with it. I have been using Yupo for a few years and love the way it takes watercolor pigment and stays unaffected by multiple applications of color. I use it mostly for my ocean scenes, you can see one here. I have to paint flat because until the paint dries it will move. I have had paintings run off the paper while carrying them back to the car. Also while camping at the Grand Canyon during a rainy night my painting became damp again and stuck to other papers. What I like about it is that you can continue to add color without the paper being affected by scrubbing or reworking and the paint continues to stay fresh and transparent. I love that the paint does its own thing and find it very entertaining to continue to work like sculpting till I find a visual result I like.
