I have a interest in Altered Books. I keep discarded book on my desk and use it as sketch book. I enjoy drawing on a printed page. I often scan a drawing and use it as a greeting cards. A teacher in Seattle saw my New Years Card and asked me to come to his school and give a talk on Altered Books.
This image is a two page sketch of a butterfly, I use pencil crayon and ballpoint pens as the are quick and don't bleed through.
