Nine

Well that's it! I've got 36 letters and digits. I'm happy that I showed up daily for this creative exercise. Restricting myself to a certain grid, number of colors and shapes was helpful because I was forced to think in a new way, in order to come up with the a way to depict each letter and number despite the limitations I set up. If I do this again next year I would definitely keep the design more simple. In hindsight I didn't need so many patterns and the design may have been stronger.
