'Tonnau Rad' Kids Welsh Surf T-Shirt

This design uses a bold circular layout and flowing linework to suggest the movement of the sea. A curling wave wraps around the scene, framing a surfer in silhouette and giving the design a clear sense of motion. The phrase “Tonnau Rad” brings together tonnau, meaning waves, with a borrowed bit of surf slang. “Rad” comes from skate and surf culture - as in “those waves are totally rad.” It creates a neat link between Welsh language and global surf culture. The repeating curves of the wave add a steady rhythm, similar to old surf posters. The circular layout keeps everything balanced, with the wave carrying the design. A clean, surf-inspired graphic built around good waves and easygoing energy.
