Origami around the world has benefited enormously through its use of a wide variety of papers. In particular, handmade ones are especially desirable because their long fibers confer exceptional strength. However, where do these papers come from? In this lecture, I will explore the plants and people that produce the wide variety of handmade papers many origamists use today, and why that connection to origami is important. I intend to be presenting some videos that show fiber harvesting and papermaking.
