I also label all of my paints, colored pencils, and other supplies, so that I know their colors. I have found that these techniques work quite well. They have given me the chance to have my work hung anywhere from living rooms and dens to the White House and the Smithsonian. Painting, as well as drawing, is difficult for many people. But for me, the creation of these art forms continues to be possible.
Art is created from within, through one's mind and passion.
It is affected by experience and the environment. Like anything, art is possible if you have enough motivation and creativity to do it. The dream of that second grader, who was so taken by the field trip to the museum, is still alive and probably more so than ever.
