This is my latest tangle pattern – Crosseyed. Apparently, a cross-shaped pupil would be an optical nightmare. Who knew?

A bit of subtle shading can increase the impression of spherical eye balls…
If you haven’t discovered it already, here’s the link to my tangle pattern gallery. There are now over 125 of my step-by-steps to original (as far as I know) patterns for use in zentangle inspired art.
