A portable jigsaw puzzle storage case and workstation is provided generally comprising an outer cover which encloses a sorting tray and a workstation therein. The workstation generally includes an assembly tray having an assembly board and a frame. The frame extends around at least part of the outer periphery of the assembly board, and is joined thereto by an integral hinge. Preferably, the assembly tray is formed of corrugated fiberboard. Further, a method of producing an assembly tray is provided. The method generally comprises the steps of providing an assembly board having a first half and a second half, cutting out an inner section of the first half to define an outer peripheral strip, scoring the assembly board at a boundary line where the first and second half meet, and attaching the outer peripheral strip to the second half to form a frame on the second half of the assembly board. The cutting step may further include the step of cutting the inner section to form a sorting tray.
