Mack is a humanist sans serif inspired by the natural, brush-made variations of details originally rooted in geometry. The spark for this project came from lettering on a map of Mackinac Island whose angled terminals, pointed peaks, and variation of proportion were all details that set it apart from the strictly geometric forms it appears to reference. Rather than copying the few letters there and extrapolating them into a whole font, Mack is an original design following similar principles. Its structure and contrast resemble those of mid-century geometric typefaces while its curves and terminals are angled to emulate the stroke of a brush.
