I wanted to create a quick overland map to give to my players in our exploration themed campaign. I wanted them to have a sense of the geography of the world, but not fill in any cities or anything. I used the black and white overland style. It doesn't look like much but...
Definitely will do that for a treasure map. This one was actually supposed to be quickly drawn by the players, so I thought tearing or burning it would be a bit out of place.
As for why they used sketchy old paper in the first place... shut up :)
Actually, microwaving gives a very nice effect for aging paper too! And much faster! Great for those times when you are doing some last minute prep and have to get it done fast. Nice effect, though! And a very nice minimalist map!
