Zusammenfassung:	The invention discloses methods of making frames for electromagnetic (EMI) shielding apparatus. An exemplary method generally includes steps of forming a frame, wherein the frame is provided with at least a first frame portion, a second frame portion, and a common sidewall, and the common sidewall includes at least a portion shared by and connecting the first and second frame portions. The second frame portion is repositioned from being disposed within a footprint of the first frame portion to outside the footprint of the first frame portion. Another exemplary embodiment includes a frame having first and second frame portions wherein the second frame portion is of a size sufficient to fit within an interior region defined by the first frame portion; and the first and second frame portions share at least a portion of a common sidewall having a bendable hinge portion that connects the second frame portion to the first frame portion.
