A vehicle trim component defining a storage pocket for mounting on a door panel is formed from first and second portions integrally attached to one another by a living hinge, to initially form a clamshell-type structure. The first portion defines a back wall of the storage pocket. The second portion defines a pair of opposed side walls of the storage pocket. The first and second portions are folded together about the living hinge to form the storage pocket. At least one fastening mechanism connects the first portion to the second portion when the first portion is rotated about the living hinge to the final assembly position adjacent the second portion.
