Just like with writing equipment it is important to think about what kind of paper feels most right for your specific setting. What is a little bit trickier with paper rather than other equipment, is that what is historically accurate does not necessarily feel right to most players. As an example, there are periods of time where paper was supposed to be as stark white, thin and smooth as possible, yet people generally have a preconception of historical papers being thicker, a bit uneven and not too white. This creates a contrast between different wills, ambitions and aesthetics, so it is preferable to think about which direction you want to take your larp. There are also ways of making a paper more special; for example embossing or a printed letterhead.
