Entropy Magazine interviewed me about my 2016 comic. And I even made them a special comic about my "origin story." You can check it out here: http://entropymag.org/the-new-comics-liz-walker/
It's probably a dumb process, but I make my comic by sketching in a sketch book, inking on tracing paper, and then scanning. The tracing paper part is a habit I picked up from screen printing. Anyway, this is what a stack of 23 comics on tracing paper looks like.
