I learned how to make crispy digital doodles from one of my favorite cartoonists, Everyday People Cartoons by Cathy Thorne, whose method I found by researching her online (i.e. vigilant google stalking).
I draw on acid free paper, use a pencil and eraser for a draft, and micron pens to trace over the final drawing. I then scan to my computer, and edit/color in software (I use Pixelmator, a simplified version of Photoshop). In my earlier doodles, I was “scanning” by taking pictures on my phone. Having a real scanner made a huge difference for me.
My doodle skills are frozen in seventh grade and I’m okay with that. I don’t miss having eraser dust in my life, but I also kinda love it.
