Well, apparently they were back then and still are today for people of all ages. People are making the adult coloring books bestsellers on Amazon! At the time of this writing, eight of the top twenty books on the bestsellers list, are coloring books for adults. There must be something behind this recent growth in interest.
Adult coloring books are all the buzz of late. It is clear that it revolves around colored pencils or crayons and coloring pages. But, it is just coloring, right? How can something like staying within the lines be a benefit to me? I grew up during the time of doodle art - remember those? You got a pack of felt markers and elaborate black line drawings on a number of themes. I would spend hours coloring these in! Little did I know then that coloring pages were a benefit to my well-being.
