Adult coloring books are unquestionably all the rage at the moment, but what will keep the grownups away from stress when the fad dies down? Little, Brown and Company believes that a new mania will promptly rise, in the form of connect-the-dot books.

"A lot of people think that's where this will go," Carina Guiterman, assistant editor for the said Hackett Book Group division told Wall Street Journal. "We haven't seen the end of creative expression," she went on to say.

In fact, Little, Brown and Company will be kickstarting a series of adult connect-the-dot titles by releasing the first two books early next year. As per The New Republic, the publisher foresees a decline in adult coloring book demands next year, and an increase on what is being forecasted as the next creative grown-up craze.

Publishers believe that 2015 was definitely the year of adult coloring books, with higher demands for colored pencils due to the success of illustrator Johanna Basford, with her coloring books "Secret Garden" and "Enchanted Forest."

As it turns out, eight of the 20 bestselling books on Amazon are actually coloring books. Nevertheless, publishers remain positive that connect-the-dot books will take the center stage in 2016.

After all, the popularity of the former is not from the idea of throwing hues and tints on elaborate illustrations, but from the benefits of the activity's stress-busting power.

Also with coloring books, grownups have thought up various activities and gimmicks to make it more fun.

Bill Sannwald, manager of the North Park Branch of the San Diego library, figured that coloring activities are not just for kids, and so he set up crafting sessions for adults. Unsurprisingly, more public libraries followed suit.

Michael O' Mara is another publisher that benefited from the craze. The company published "The Creative Colouring Book for Grown-Ups" back in 2012 in the UK, after a staffer was embarrassed about her mom actually taking pleasure in coloring a children's book. Needless to say, it was a hit.

Coloring programs and workshops also became a thing in the midst of the trend. Sessions now exist that allow adults to get together, color and tell their "feelings about" their artwork. Some programs aim to understand the meaning of colors.

Lastly, the popularity of the activity also made those who already love coloring more comfortable about it. "Some people like to work out. I like to color," Chicago resident Jenna Gaydos told Wall Street Journal.

Whether or not connect-the-dots will make all of this obsolete, the world will soon find out either way.
