While married to Ruskin, she modelled for Millais' painting "The Order of Release", in which she was depicted as the loyal wife of a Scottish rebel who has secured his release from prison. She then became close to Millais when he accompanied the couple on a trip to Scotland in order to paint Ruskin's portrait according to the critic's artistic principles. During this time, spent in Brig o' Turk in the Trossachs, they fell in love. While working on the portrait of her husband, Millais made many drawings and sketches of her. He also sent humorous cartoons of him, Effie and Ruskin to friends. She copied some of his works.
