Don't we all sometimes have problems folding back some of those big maps. You know the ones you have to fold like 5 times... If you are going on a trip somewhere, you can make your own map. Print it on a paper and fold it like a pro :-) This "instructable" includes lots of images to make it easier to understand. I have tried to use images instead of text as much as possible.
This is the endresult... last image is a gifanimation showing the map in action.
I've made a template with folding lines that I will use in the beginning to make things more obvius later on. You can download this template (Illustrator file) from the zip-file below or use the PDF file.
