How to make your own large painting

So here is my sketchbook. I drew the final picture and now I need to transfer it to a large canvas. The method I'm going to describe here is the old way of doing it. Contact me if you want to know about the new way (but you will need to shell out for an opaque projector). The old way is good, though. The technique is hundred's of years old. Let's get started. You will need a ruler, a yardstick, and some pencils.
