In 1920, Jakac returned to Novo Mesto and became the bearer of The Spring of Novo Mesto, an avant-garde movement in literature and fine arts, which included also the poets Miran Jarc and Anton Podbevšek, the painter Ivan Čargo and the composer Marij Kogoj. In 1924, he settled in Ljubljana. At first, he earned his money as a woodcut illustrator at the liberal newspaper Jutro and a professor of drawing at the Second State Gymnasium in Ljubljana. Three years later he gave up his work and became an independent artist. At that time he also travelled extensively, for example to Paris, Tunisia, the Americas and Norway, and married Tatjana Gudrunova, who profoundly influenced his work. In 1932, he published his memoirs and letters from America in the book Odmevi rdeče zemlje ("The Echoes of the Red Earth"), in cooperation with his friend Jarc.
