Here is the tentative artwork for the Darwin t-shirt. It would be printed as two layers, black and white. Alternately, I could do brown and white as the two ink colors. The blue represents the t-shirt color, so that could change, although I’ll probably just do one shirt color for the first run.
Feedback is welcome, because I’d rather re-do the source artwork several times than end up with t-shirts everyone finds disappointing.
I’m still in the process of researching which screen printer I want to use.
