Start with a large rectangle. Look at its shorter side and use that length to draw the largest possible square inside the rectangle.
Now ignore the square you've already drawn. Look only at the remaining rectangle (13 cm × 21 cm). Use its shorter side (13 cm) to draw the next largest square.
After drawing each square, focus only on the rectangular space left over. Find its shorter side and draw the largest possible square inside it. Continue until the entire rectangle is divided into squares.
Draw a quarter-circle inside each square, ensuring all the curves connect smoothly to form one continuous spiral.
Make your spiral attractive by colouring the squares blue and yellow, as shown in your reference. Label them with the Fibonacci numbers: 1, 1, 2, 3, 5, 8, 13, and 21.
