Smaller drawing boards are produced for table-top use. In the 18th and 19th centuries, drawing paper was dampened and then its edges glued to the drawing board. After drying the paper would be flat and smooth. The completed drawing was then cut free. [3]: 1-2 Paper could also be secured to the drawing board with drawing pins [4] or even C-clamps.
