If any additional evidence is needed that I sometimes totally fail to have my finger on the pulse of the book-buying public, the advent of coloring books for adults qualifies. That's definitely one I didn't see coming.
Publishers Weekly reports that "the demand for coloring books in the US continues to surge." One of the books that started it all, Secret Garden, has 1.5 million copies in print around the world. The pitch is that coloring is therapeutic rather than regressive.
One line of books has perforated pages so you can frame your masterpiece. Or you could put it on your fridge door for your kids' friends to admire when they come over.
Maybe it's a drastic response to the perceived need to be available and online 24/7 but I have to say I still find it a little strange. I wonder whether we'll see an upsurge in jigsaw puzzles and paint by number kits, too?
PS: when you're an adult, is it OK to go outside the lines?
