How can I create unique textures and patterns in my watercolor paintings using the technique of adding salt?

To create unique textures and patterns in your watercolor paintings using salt, first apply a wet wash of watercolor on your paper. While the paint is still wet, sprinkle salt over the surface. The salt will absorb the pigment and create interesting patterns as it dries. Experiment with different types of salt and amounts to achieve various textures and effects in your artwork.
