When I attended my certification for Zentangle. I met the most wonderful people one of them was Leslie Crumpler. She worked for Sakura at the time was also getting her Certified Zentangle Training.
We were asked to looking around the building and grounds to see if we could fine something to create a tangle from. This was Leslie's Fungees.
I have changed things just a little. Making it a little more free had style. Leslie's shows her tangle here.
I have step-outs for the free hand tangle below.
I love how this looks so organic.
