Abstract: A soap holding device for holding a bar of soap. A water permeable sheet of material is provided that has a periphery defined by a first edge, a second edge, and two side edges. The sheet of material is folded to have overlapping sections so that the sheet of material proximate the first edge overlaps the sheet of material proximate the second edge. The side edges are sealed closed to define an internal pocket within the soap holder that is only accessible through an open slot. The open slot extends between the overlapping sections from the first edge and the second edge. A bar of soap can be inserted into the internal pocket by sliding the bar of soap between the overlapping sections. Once the bar of soap is inside the internal pocket, it becomes trapped.
