Did you know? The first paper ever created was in AD 105, when Ts’ai Lun, a Chinese scholar, combined a wet pulp of bark, linen, and hemp fibers and let them dry. Before this, people wrote on cave walls, stone tablets, and papyrus. The invention of paper is one of the most important in history. Today, North America’s annual demand is about 7.4 billion pounds of paper! But all paper is not created equally… and your choice could make or break the quality of your project.
