In fact, my suggestion is that you should draw the wheel Guo roughly first and know the approximate range.

Let's draw a picture with the knife slightly, because the fine drawing can also be modified in the sketch.

If you are a novice, you really don't understand it very well. You can find some simple pictures of dragons, stick them on the melon skin roughly, and then try to adjust them according to the pictures. In this case, the chances of making mistakes should be reduced, and it is paper, and it will fall off when it gets wet ~ it won't affect the melon skin ~

But if you want to sharpen your knife skills, it's good to practice more, so you can practice and make perfect ~
