I love all of Grace Danico's illustration work, but by far my favorite are the drawings she's made with what look like your ordinary, everyday Crayola crayon and color pencil. The consistent colors of blue and deep orange feel so friendly and fresh, that I just want her objects to come to life so I can play with them.
Grace Danico is also the Illustration Editor of one of my favorite graphic blogs, Grain Edit. Be sure to spend some time on there as well. Now smile, because her artwork will make you happy.
