A while back I participated in self-improvement challenge among maybe hundreds of other designers, illustrators and typography entusiasts. The challenge; make one letter each day, starting on A going to Z, then 0 to 9. We would post it on the same day, following a calendar. With the image we'd hashtag the letter of the day with a custom prefix to only show those that participated. I got in a day late and started with C. Today I finally got the A done and is posting the whole set. Note that it was not meant to make a font, but find a way to show a letter, in your own or any style, subtle or obvious.
