The most beautiful things in the creating of the child are his "mistakes." The more a child's work is full of these individual mistakes the more wonderful it is. And the more a teacher removes them from the child's work the duller, more desolate and impersonal it becomes.
What adults call 'wrong' in Child Art is the most beautiful and most precious. I value highly those things done by small children. They are the first and purest source of artistic creation.
