Cubine is another 3D optical illusion type of tangle pattern. Variants include using straight or curved lines for the frame and different shapes for the solid areas, shading, and filling shapes with thinly-spaced lines. I tend to like these architectural type of patterns very much. So orderly. 
Cubine is an original Zentangle® pattern designed by Maria Thomas. The link to her illustrated instructions for drawing this pattern is here.

Hi Kate, the only patterns I include step-by-step instructions for on my site are patterns I’ve created. All other patterns contain a link to the pattern creator’s own illustrations of the steps for drawing their patterns.
