You did it as a child and maybe you should start again. Coloring relieves stress and helps keep your brain sharp. Millions are doing it again, how about you?
Dover Publications has sold more than 3 million adult coloring books with titles like "Flower Fashion Fantasies." Quarto Publishing will have 1.3 million in print this year ranging from mandalas to fairies. "Secret Garden: An Inky Treasure Hunt," by one of the genre's most popular illustrators, Johanna Basford, remains a top seller on Amazon two years after its initial publication.
In fact, adult coloring books occupied as many of eight of the top 20 slots in a spot-check of Amazon's best-seller list this week, including "Creative Cats" and "Adult Coloring Book: Stress Relieving Patterns."
"We cannot print them fast enough," said Amy Yodanis, Quarto's head of marketing. "We are getting orders of 60,000 at one time from some of our biggest retailers."
There are coloring clubs, coloring contests and a frenzy of coloring posts on social media. Parade magazine devoted a Sunday cover to the trend. Dover plans a national coloring book day on Aug. 2.
