Open a new pit, leather art watercolor book binding production

The watercolor group practice I participated in earlier has graduated. As a tool party equipment controller, I think it’s time to arrange a watercolor book for myself! Most of the watercolor notebooks on the market are fabric watercolor notebooks, and the high-end ones such as Jiukoushan are only made of PU material. There is nothing you can do about it. If you have the conditions at home, I will teach you how to make leather! In this tutorial, I will explain in detail the difficulties of the binding process from four aspects: "paper binding", "cloth making", "ring lining making" and "book cover making and fitting". I have read many tutorials on binding and opening. The difficulties were not explained clearly in the combined part, and these two parts were indeed a bit abstract. I took the hardcover notebook at home to study and practice for several days, summed up some experiences, and tried to analyze it as clearly as possible for everyone. Materials: watercolor paper, leather/fabric, gray board, needle, thick cotton thread, fine cotton thread, white glue. Tools: shaping rod, utility knife, steel ruler, clamps, film.
