I finished attaching them to the book then used watercolor to give them a little color. I chose watercolor because it is more mellow and it is the same medium that is used in the cover art in the original Winnie-the-Pooh books. I wanted to keep the feel of E.H. Shepard's characters.
I was really happy with how it turned out; however, some of the strips didn't glue down very well so if I were to do this again, I would spend more time covering the characters in the lines from the book.
