Celtic knots, drawing a more complex finish I

Hi friends!

Something that makes artistic work interesting is looking for more than one solution or approach to an idea or project.
The drawing I show now is a variation of the previous one, developed in several posts as tutorials, where I tried to teach you some techniques of Celtic knotwork.
This new version is a little more difficult but interesting due to its complexity and aesthetic finish.
I'll let you see it...

-----------------------------------------------

You'll notice that the grid above is the same one I drew in the previous knotworks.
However, the following are different. I'll draw three grids separately, one for the external area of ​​the circular shape, another for the internal side and a last one to connect the knots.
Here I have started with the outer grid.

Note that the outer grid is six cells wide and the inner grid is four cells wide.
The small middle grid is 6 x 4 cells.

All the interlaced lines have been drawn and the connection between the inner and outer knots has been made.

The process of joining the knots is widely explained in several previous posts, you can always go back to them from the beginning. In this drawing, nine knots have been joined together to form a single endless loop.

I wish you a very nice day!
