The challenge from the Diva this week is to use a tangle pattern called '8s Parte Dos'. It's a tangle that really requires extra concentration. And true to my usual form, I made it extra tricky for myself by doing it as a monotangle zendala. I made a few mistakes - especially around the edges - but in Zentangle, there are no mistakes so I'm accepting it as it is and enjoying it. I started using the sphere template from Margaret Bremner but I modified it a bit.
I used one of my colored tiles and a black Micron pen. Then I shaded with a purple colored pencil and added a few highlights with a yellow pencil.
