Yeah, like beaky said, technically it does matter as what you are presenting is supposed to look professional. Although, if you successful in making your project look professional, there's no need for the fancy paper, and the colourful backdrop etc etc.
You should suit the presentation of your folio to your individual project.
Speersy, you also need to realise that the markers will never give "bonus" marks. They have a set marking criteria, and they look to see if things are done, and give you marks when the individual criteria have been met.
