I really enjoy doing fake logo designs, signs, packaging, internet pages, memes, etc., etc. for use in my comic, Teenage Gender Neutral Turtles. Sometimes when I feel stuck on starting a page, I go draw one of these to get started. It’s a good way to get moving.
Here are a couple of book covers and some money that appear very briefly (and at a very small size) in chapter four! Since they’re done, I can easily drop in there again if it makes sense in the future!
I think my favorite part is actually the “TEEN READS” slug up in the top right of the radish book cover.
