Have you ever looked at a word up close and noticed some fonts have little lines attached to the ends of letters? Those are called "serifs." When a set of letters has them, they’re called “serif fonts” and when they don’t have them, they’re called “sans serif fonts.” This month we're challenging you to get creative with serifs (or sans serifs!) by making your own font! And since Pi Day is happening up on March 14th, (because of the number Pi) we want you to focus on creating a new font for numbers!
