Voysey was a distinguished designer of flat patterns for wallpapers, fabrics, carpets and tiles. It was Mackmurdo who first introduced him to the techniques of wallpaper design, and some of Voysey's early pattern designs incorporated more restrained versions of the swirling motifs beloved by Mackmurdo and the Century guild of artists. Voysey sold his first wallpaper design in 1883; by the late 1880s his reputation as a wallpaper designer was established at home and abroad, and he was still selling pattern designs in 1930. His career as a pattern designer was thus longer and more prolific than his career as an architect. But it was also complementary to his architectural career, because selling patterns supplemented his income in the lean years of his architectural practice, before c. 1895 and after c. 1910.
