DracosDerpyHoof put together an 18 page SU coloring book, aimed at adults. Of course, there's no age limit on coloring, and all the images are relatively SFW, so the coloring book is open to everyone. And guess what? It's totally free! Prints out some pages for your kids or a family function, and spread the show around!
