The next thing you need to learn is : HOW DO YOU PAINT " INVISIBLE BLACK LINES " on a on white canvass ?? And make the black lines invisible on a white canvass. Here is how : (1) White clothe is usually flourescent ( because of an enzyme they use in the bleaching of white clothe ) (2) BUT white chalk, white paint, and white crayons are not usually flourescent. (3) Therefore, when you paint white paint on a white clothe canvass it is (A) invisible with white light BUT (B) the white paint becomes a BLACK LINE on the white clothe with a black light. This creates a very dramatic effect in your presentation. (C) The same is true of regular WHITE CHALK AND WHITE CRAYONS they all become a black line on the white clothe. (NOTE: a WHITE PAINTED CANVASS does not work this way, only a regular bleached white clothe. So a canvass from the art store will not produce this effect. )
The above picture of the Statue of Liberty is a good example of the White paint, white chalk, and white crayons becoming black lines with a black light.
WECOME TO THE WORLD OF INVISIBLE PAINTS !!!!
