When I was a teenage child, I had made a coloring notebook, combining the colorful images of landscapes, wildlife, aerial life, aquatic life and so on. It was such an interesting hobby, that my schoolmates were also showing their interest to simulate it. Thus, this is a hobby - all children appear interested to garner the coloring-pages and cards to enjoy their life at their best. You might speculate that, in what sort of colors or images my kid is interested in.
