Abstract: In one embodiment of the present invention, a sheet folding system is provided. The sheet folding system includes a first wall, a second wall coupled to the first wall, a third wall and a fourth wall coupled to the third wall. The walls are configurable in a first configuration in which a chamber adapted to receive a sheet is formed at least partly by the walls. The walls are also configurable in a second configuration in which the first and second walls are substantially coplanar, the third and fourth walls are substantially coplanar and the chamber is substantially collapsed. The sheet folding system can include a fastening device adapted to hold at least a portion of the sheet substantially in a desired position relative to the first wall. The sheet folding system can include a position indicator. The sheet can be a sheet of paper.
