“Women’s Work” is work that women are normally better than men at such as nurturing children, cleaning things, and making food.
Art is something made with artistic intent, vision, and skill. Art is not everything, but art could be anything.
“‘Women’s Work’ is also Art” means women should be respected for the art that they make and nothing they make is any more or less valuable than something a man makes. It means that their work is equal to everyone else’s.
