Do children need cantilever to learn calligraphy?

Hello, I suggest cantilever, because it can make the words bigger, and it is better to write standing up, so that the scope of activities is wider.

Regarding learning calligraphy, I think tools are also very important. If you want to have a better brush, you can find this article and read "Top Ten Brush Brands in China (with brush selection and maintenance methods)". This article has written a lot about brush selection, hair opening, pen holding posture and so on. I hope it helps you.
