Do you like to doodle? Have you heard of Zentangle?
My first Zentangle
This art form is actually meditation. The repetition of patterns is supposed to help you go into a calming, destress zone.
No eraser allowed here. Just like with life, if you screw up you learn to incorporate those little mistakes into something meaningful.
There aren't many rules here either. Wanna draw something upside down? Go for it. Wanna add in a flower or maybe a bird? Go for it. Wanna do an endless swirl mimicking Suessville? Do it!!!
Here's a cute video on this interesting artform. Give it a try!
