As the campus minister for Global InterVarsity, I was responsible for all of our organization's marketing and branding. Because I was designing under InterVarsity's national brand, I had some limits on color palette and font choice. Our audience was always international students with a broad range of English proficiency. Keeping this in mind, I was careful to create simple, easy-to-read posters and flyers with lots of color and illustrations* when applicable.
