An organizer container includes a fabric body movable into an expanded configuration, wherein the body defines a bottom and above the bottom, a parallelepiped-shaped enclosure divided into three compartments by first and second parallelepiped-shaped divider panels spaced from each other and perpendicularly oriented relative to the bottom. The container also can be moved into a first partially expanded configuration wherein only two compartments are established, with the first divider panel being held substantially flush against a first end wall of the body by a first holding mechanism. The second divider panel likewise may be moved flush against the second end wall and both divider panels can be moved together to entirely collapse the container. A stiffener can be moved within the enclosure to be sandwiched lengthwise between a divider panel and an end wall and/or between two divider panels.
