Draw the outline of the picture of your interest in a paper.
Moisten the paper with water with the help of your paint brush. But, avoid creating puddles of water in the paper.
Paint the picture with the water color.
Now, sprinkle some salt on the wet painting.
Let the painting dry. It may take some time.
Once the painting is dry, shake the excess salt off.
Now the painting is done.
