Sand n Sketch
Sand n sketch was originally named "Mystic Mountain Beauty" also thought to be "Pareidolia" def: the tendency to perceive a specific often meaningful image in a random or ambiguous visual pattern. My first Sand n Sketch image is shown to the right:
Sand n sketch is created by scratching/sanding the surface of this "unique" rock with a small piece of 320 grit sandpaper using a few drops of water. When the perfect consistency of the water and white powder from the sanding of the surface of the rock is achieved. I have only a minute or two to complete the picture or my surface will start to dry and will need to start the process over again.
When I discovered this cool 3D image on the rock I immediately tried to do it again. Every time achieving a different result more beautiful than the first one. I did not use chalk pastels for colour until several years after the initial discovery.
Below are some examples of this affordable New Art Form.
