Direct Observation
This assignment can be done on paper with colored pencil or paint. It can also be done on wood, tile or floor covering to make it look exceptionally real.
Trompe L' oeil eye catchers in a home by artists Eugene Perreault and Keith Babcock
You really don't have to paint the detail if you can capture the "look". Think impressionistically. In fact, realize that it's the "first impression" the grabs the viewer. Make you image identical to what you see. The material you draw or paint on should be rectangular and neat.
If you would like to try to really fool the eye, try painting it on an actual piece of flooring material that is not too glossy to allow paint to adhere. I can supply wood or tile to anyone who desperately needs it but I prefer you seek something leftover from a home remodeling project.
