Since there is no map, I have to dictate a plan to the landlord to see his understanding ability.
Draw a square. Must be standard, or the designed picture will feel bad.
② Two diagonal lines connecting the midpoint of the square and the opposite side of the square (that is, the drawn line is a "meter").
③. Make four circles with the four vertices of the square as the center and half the side length of the square as the radius. You can find that the four circles are just tangent.
If the landlord wants to be more beautiful, he can take the next step. )
(4) Still centering on the four vertices of the square, gradually narrowing the radius and drawing many quarter circles.
The above is the "shape" of this work, and you can continue to color it.
Method: Color every other figure. It's good to use water-based pen.
This is an ordinary graphic design pattern.
