My sister wanted a sign to use while sampling a coffee with not very much text that people can look at and feel like they learned something. As "not a graphic designer" and someone who prefers long form writing this is very much not playing to my strengths, but here's sign #1, made with the GNU Image Manipulation Program.
Found my first coffee roaster while cleaning the basement. This was useful to demonstrate the changes coffee goes through in roasting before we were roasting our own. It also had some time roasting samples, but the control on this is limited and consistency is bad. Eventually I was able to do better roasting samples in a production roaster (basically roasting by sound as that's so far below minimum batch size that visuals and instruments are unavailable). These days I have something appropriate.
