Art therapy: Coloring Page – A Dog is Playing with a Beautiful Butterfly is an online game and printable coloring book that never ends. Coloring instills a sense of style, because young artists will choose and combine colors themselves. The movements train the hand for writing, develop fine motor skills. A young artist will be able to create a personal collection of finished works and share the beauty with friends! Creative Commons Attribution-NonCommercial 4.0 License.
