Last week, I asked our readers their thoughts about coloring books, and I immediately got emails sharing what you love about coloring, what you color and what you color with. It was such fun. I compiled many of the comments, and you can read them here. Inspired, Tom, along with our intern Isabel, created one of our signature bookshelves, "20 Coloring Books for Adults: Inky Adventures, Stress Relievers, Mandalas and More," which features 20 coloring books to delight you. But what to color with? Have no fear, Nicole from our staff compiled a list of colorful pens, crayons, pencils --- and even an eraser --- which you can use to color your pages. I confess that I covet the 150-pencil collection...maybe they even have turquoise and periwinkle blue.
