In this one, I kept layering watercolor paint. Used a brush. Used a straw. Used salt. Used some powdered paint. I think I finally like it. Took long enough.
This time, I put drops of one color down, blew on it with a straw, and let it dry completely before adding another color. Only three colors are on here, so you can see that water color paints go from dry to wet and mix very easily.
