On TheDollPalace.com, for example, dolls of every shape and size are available for children to play with and create, and then favorites are created into coloring pages. When dolls and coloring pages are complete, there are still interesting articles to read, personalities about the dolls to create, contests to take part in, and even forums and chats to visit to get to know other doll and coloring enthusiasts.
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.
