premise: To give paper an aged look
hypothesis: To give paper an aged look, preheat your oven to 200F. Crumple up your paper, uncrumple it and spread it on a baking sheet. Pour a little hot chocolate over it and use a sponge to dab it here and there, to make it less even. Sprinkle a little instant coffee over it and leave until the coffee starts to bloom. Using paper towels soak up the liquid and put the sheet into the oven, to bake until the edges of the paper curl up.
