Coloring books generally have a theme of sorts. It might be that they are based on a Disney movie, or it is about animals, or vehicles, or something else. When selecting books for your children, remember that they will want to express their creativity, and will have a lot of fun with any coloring book, but will be more interested in a coloring booklet with a theme that appeals to them. Choose a color book that features their favorite characters, or the item of interest in their life. For example, if your little boy just loves trains, get a Thomas the Train coloring book. If your little girl is as girly as they come, look for the Disney Princess coloring book, or possibly Strawberry Shortcake.
After watching how mesmerized she was while filling in the images with her newly sharpened pencils, I decided I wanted to color as well. Although the images I colored werent exactly inspirational to me, I enjoyed the experience overall. The next day, I decided I wanted to get my own coloring book with a new set of colored pens. I bought a book full of pictures of mandalas (a circle with complex designs in it). The designs were beautiful and I could imagine them once I filled them with color.
