Who says crayons and coloring books are just for the kiddos? The trend of adult coloring is sweeping the nation, with millions of coloring books for adults bring sold. Barnes & Noble celebrates this reversion to childhood with a FREE All-American Art Unwind Event on Saturday, November 14 from noon to 5 p.m. Stores will give customers the chance to take part in a nationwide coloring project designed by artist Millie Marotta. They can personalize with color a collection of greeting cards and envelopes. And also, experiment with color, different illustration styles and art supplies featuring some of today’s bestselling coloring books. Most activities are FREE. All Barnes & Noble stores are participating, but, as always, we suggest you double check that your nearest location is joining in the fun. And, remember, we at MHOTC don’t believe you have to stay within the lines!
