How to make seals at home

Look up Shuo Wen Jie Zi first, find the word you want, lay it, turn it over and print it on the radish, and then carve it. Why do you have to use radish? It's kind of ridiculous. In the past, when people practiced, they would collect a lot of dry clay (some sculptors would make plaster), write the layout of seal script on rice paper, and then turn it over and stick it on clay or plaster for carving. When the rice paper is dry, even the rice paper is directly engraved. When it is almost the same, take off the paper and adjust it slightly, and it is finished. Hey, what do you think?
