"I personally love adult coloring books and have been using them for about a year now," Cory Will, Creator of Color Me Book, told BuzzFeed. "I thought it would be awesome to upload photos and make my own personalized adult coloring book. I was shocked I couldn't find it anywhere, so I reached out to a friend who runs a print shop in Los Angeles to see if he could make them for me. When I showed some friends, they wanted to order their own. So I decided to build a website to see what kind of response we would get."
