The Arts and Crafts movement of the mid-19th century emphasized handcrafted wood, pottery, and stained glass with nature motifs. Products were made by individuals rather than factories. Art Nouveau in the late 19th century featured whiplash curves and nature designs in metal and wood. Some used mass production while others valued craftsmanship. Art Deco in the 1920s-1930s had zigzags, sharp angles, and stepped designs influenced by skyscrapers.
