Sustaina is a display font created for startups and brands that pursue sustainable services, products, and technologies. This font enables companies to communicate with users through their marketing, making their messages more attractive and memorable. The final goal of this project is to make this font contribute to their success — and help pave the way for a sustainable society. I designed the basic letter shapes to be elegant and sharp, so that their messages will come across as sincere and trustworthy. What's more, this font also features natural motifs and organic curvy letter shapes as alternative styles that enable users to deploy this font more flexibly. The alternative style has three patterns, depending on their themes.
