Beautiful watercolor paper in an accordian-style book! This paper has been made using the same techniques for more than a hundred years. Now they are offering it in a zig-zag book format. This is a fantastic format for a single long composition or to make a series you can view all at once. Do a series of small sketches while you are traveling. This also makes a perfect format to play the 'exquisite corpse' game (no dead bodies involved).
