Sonia designed costumes for two films: "Le Vertige" directed by Marcel L'Herbier and "Le p'tit Parigot", directed by René Le Somptier, and designed some furniture for the set of the 1929 film Parce que je t'aime ("Because I love you"). During this period, she also designed haute couture textiles for Robert Perrier, while participating actively in his artistic salon, R-26. The Great Depression caused a decline in business. After closing her business, Sonia Delaunay returned to painting, but she still designed for Jacques Heim, Metz & Co, Perrier and private clients. She said "the depression liberated her from business". 1935 the Delaunays moved to rue Saint-Simon 16.
