If you like watercolor painting then this activity is for you. Jean from The Artful Parent, had her daughter work with 2 watercolor techniques at the same time. They put rubber cement all over the picture, then painted with the watercolors and then sprinkled salt onto the picture. The salt added a very interesting texture which they rubbed further into the paper. They then took time rubbing off the rubber cement once it was dried which left some beautiful white lines running through the artwork.
