1. First, prepare a piece of paper with characters' faces written on it, cover it with a rubber stamp, then coat it with nail polish, then spread a layer of plastic paper and scrape it several times with a tool.

2. After removing the paper, pick up the carving knife and carve along the lines of the characters. Start with the hair and work down slowly, and dig out all the extra erasers around.

3. Then continue to carve the facial features below the hair, except the scars on eyebrows, eyes, mouth, ears and face, and dig them out to expose the parts that need to be left blank.

4. Finally, continue to carve the clothes of the characters down slightly, and the rubber stamp of the cartoon face is completed, and the inkpad can be used directly.
