I did this last Saturday.
It was weird, I saw things in the paper and just traced what I saw.
I think I drew like 10 pieces in 1 hour, none of them looked particularly good, but they FELT good to draw.
I learned that it doesn't matter if I don't know what to draw, just drawing and feeling like it mattered was good enough.
However, I have anxiety and it kicked in halfway through, I started thinking in circles and paradoxes, got a nasty migraine.
The feeling of "Everything is connected, my teeth feel weird, I'm being mind controlled by music, the sky wants me dead" is something I will never forget.Don't do drugs kids, just learn to have fun while drawing, you don't need shrooms.
