Calligraphy felt is a kind of calligraphy tool used by beginners of brush calligraphy, and its function is to prevent paper from seeping out and polluting the desktop.
Generally, it is used by beginners or primary and secondary school students. Generally, great calligraphers don't use felt, but write directly on the desktop. However, in order to be foolproof in video calligraphy lectures, and to prevent paper from infiltrating into the desktop and printing paper from affecting the writing effect, calligraphy masters also use calligraphy felt in lectures.
Master calligraphers usually do not use felt when writing and creating calligraphy works. It is written by putting the paper directly on the desktop.
Selection method of painting and calligraphy felt;
First of all, from the material point of view, some painting and calligraphy carpets are pure wool, which can be divided into domestic wool (first-class painting and calligraphy felt) and imported wool (super-class painting and calligraphy felt), some are chemical fiber (chemical fiber painting and calligraphy felt), and some are wool and chemical fiber mixed (blended painting and calligraphy felt).
Technically speaking, some calligraphy and painting carpets are wrapped in dense cloth, some are just sealed with thread, and some are directly cut without any treatment. The wrapped wool felt is generally treated like this in high-end felt. The calligraphy and painting felt with edge splicing is also the most common felt.
This is completely uncovered, which is usually found on larger painting and calligraphy carpets. In addition, some felts made of wool are natural, while others are bleached and dyed by the latter. When it comes to dyeing, there are many colors.
For beginners, using an ordinary painting and calligraphy felt is similar to that of Mi Zige. Is this calligraphy and painting felt 50cm x? 50 cm, 50 cm x70 cm. Before buying, be sure to see the size of the felt clearly. This painting and calligraphy felt in my study is 50x70, rectangular, neither too big nor too small.
Then look at the size of Mi Zige on the carpet. Generally, the grid size on the felt is 10 cm square, and the grid size of the smaller felt may be 9 cm.
Then look at the thickness. For this kind of painting and calligraphy felt printed with Mi Zige, the felt with special quality will not be too thick, and sometimes it is really possible to penetrate too much ink. Felt with a thickness of more than 2 mm is enough for beginners of painting and calligraphy or daily practice.
Finally, it depends on whether the printing is clear. Some felt plaids are rough and irregular, and some are printed. The lines above are not clear, so the biggest advantage of this felt printing grid is that it is convenient for beginners to master the structure of a word more accurately.
