1. The paint box number corresponds to the canvas number
2. Open the paint box and find the corresponding number to draw
3. Cover the number, the paint can be thicker, if you think it is thin, you can paint it several times
4. You can paint all the colors of a number at one time. Remember to clean the brush if you need to change the number and color
5. If you don't finish painting at one time, remember to cover the paint cover. If you find that the paint is a bit dry when you use it next time, you can drop a few drops of water into it without affecting the use.
