Adults caught up in the coloring book craze now have new and more social ways to participate: through libraries and meetup groups.
Libraries across the country are holding adult coloring programs more and more in response to the spike in interest, according to the American Library Association, including New York City, Denver and Milwaukee. There are also groups popping up through Meetup.com.
"People just love this. I think they feel successful, like they've finished something," said Jane Henze, the adult-programming director at DeForest Public Library near Madison, Wisconsin. "The neat thing about it, as far as stress goes, you're concentrating on something, you're not thinking about what's going on at home or at work."
