Thank you for watching!
The size of rectangles of the grid I drew is 6cmx3cm.
Then, I used a 12cm diameter circle template to draw the wavy lines and added more lines with a 8cm diameter circle template.
The diameter of the circle : length of the rectangle : width of the rectangle =
4:2:1
This is just one example of how you can draw it. You can change this ratio as you like.
If you use a smaller circle in the same grid, you can draw more round curves.
