I paint

... by number.  This guy took me well over a year.  I honestly don't remember when I started it.  I'm working on finding a frame and a spot for it, since all of our walls are already covered in art made by real artists.

Each paint has a number on it and the cardboard came white with tons of areas with numbers on it.  I also had to mix paints to get some mixed shades.  Pretty easy!
