In the process of painting traditional paintings, will you be accidentally stained by your hands when painting? How do painters avoid getting their hands dirty when painting?

Most people who paint have encountered this situation. Pencil sketches are often stained by fingers, and the color will be erased if something happens. We must pay attention to this point in the process of painting, and cultivate habits in painting. When sketching, you can use the fingertips of small hands as support points (it is also useful to leave some small nails). When drawing colors, you can hold your right wrist with your left hand and stick your left elbow on your body as a support point. After a long time, your hands will become very stable, and this dirty picture will basically not happen.
