I figured out how to make Illustrator emulate the look of me using technical pens on shitty, bleedy paper, like I did a lot when I was in my teens. And the occasional attempt at a brush, as well.

I do not know if I will ever actually need to use this, it's diametrically opposed to how I normally like to work. But if I ever decide "nervous kinetic pen energy" is what I need, I'll know to go digging around looking for this sketch.

(Hello Future Peggy! If you ended up here looking for this, it's in a file called "curvy line union.ai".)
