Which side should I use for practicing calligraphy? What kinds of paper are there?
Both sides of the edge paper for practicing calligraphy can be used.
One view is that the rough side of the edge paper should be used, that is, the so-called rough side.
The reason is that the rough side of the edge paper will be more prone to ink penetration, and the penetration effect of smooth ink will be far less than that of the rough side. In addition, when writing, there is a feeling of struggle between paper and pen, and it is more felt when lifting and pressing. In other words, the friction between the rough side and the brush is greater, which makes it easier to reflect the pen force.
another view is that the smooth side, that is, the smooth side, should be used. Book lovers who hold this view mainly think that the edge paper itself is already very rough, so the smooth side should be used.
