This research investigates the relationship between nature and typography. By creating an experimental typeface based on texture of palm tree bark. The explores how organic might impact font design to create a distinctive visual language that unites digital typography natural aesthetics. Using combination tools hand drawings, resembles complex patterns inconsistencies bark was produced. findings provide fresh viewpoint typeface. shows can stimulate creative typographic designs.
