You'll notice that paper is one of the crafting materials commonly used for furniture and clothing in Animal Crossing: Pocket Camp Complete. The best way to get this crafting material is by completing animal requests, but only certain species hand out paper as rewards. When you compare paper to Pocket Camp Complete's other crafting materials, you might notice that paper isn't used in as much furniture crafting recipes as something like steel. Regardless, paper may be used for making special furniture, so you should start collecting this crafting material as soon as you can.
