Britanica defines Art Nouveau as the following:
Art Nouveau, ornamental style of art that flourished between about 1890 and 1910 throughout Europe and the United States. Art Nouveau is characterized by its use of a long, sinuous, organic line and was employed most often in architecture, interior design, jewelry and glass design, posters, and illustration. https://www.britannica.com/art/Art-Nouveau
I have always been drawn to nature so this new approach really resonates for me.
