I have gotten a lot of questions about my methods, especially my method of enlarging images for murals. As a result I'm going to explain my workflow for this project.
I first made a diagram of the walls I was going to painting on to ensure it would fit properly. I then drew the illustration with pen and ink.

Drawing

In this case I used tracing paper but I could have transcribed those measurements onto paper or board.
The next step was enlargement and although there are many methods of enlargement including this is the one I selected.
The method I used was to bring the drawing into Adobe Illustrator and using the print options I tiled the single image into several letter sized pages in a PDF file.
I could also have used a website called rasterbator.
I took that PDF file on a jump drive to my local print shop (i.e. FedEx Office, Staples, etc.) and had them print them out. This is far cheaper than doing it myself.

I took the resulting pages and taped them together on my floor in to create the enlarged image. The next task was to take rolls of sketch paper and trace the image onto them manually with a hard pencil (at least an HB).
Drawing enlargement
Once I have all of the drawing traced I flip over the tracing paper and traced the drawing from the back. I used graphite sticks because of their width and coverage but you could use a softer pencil (I would say at least a 2B).

I then took the resulting rolls of tracing paper and carefully taped them to the wall where I wanted the image. Then I took a fairly hard pencil again and once again traced over the image. This transfers the image to the wall.
Drawing enlargement
Once I was done I removed the tracing paper. I held onto it for a little while just in case but really could have thrown it out then.
In this case I proceeded to paint in acrylic.
