Watercolors and Salt

What a great project.
I just read an article about using Salt in your watercolor paintings with kids. You use thick paper so that the watercolor doesn't bleed through. You paint as usual and then before the watercolors dry you sprinkle table salt where you want it. Let it dry completely and then you can brush off the excess salt. The salt absorbs the color and makes the painting a little sparkley as well.
What a cute idea for your next project with your little painter.
