Can you practice calligraphy with water book cloth?

It can save paper, which is its only advantage. I can't remember the rest. Using it is not the same as wiping ink and paper. Water-writing cloth is slippery, so it is better to write directly on wool paper. That is to attract pupils who are afraid of getting their clothes dirty, and parents who are inconvenient to use ink at work or don't know much about it. Few friends who have this hobby use water-writing cloth.
