A shutter for covering for architectural openings having non-conventional geometries. The shutter may be used for covering a wide variety of shapes of openings, including arched, curved, circular, oval, triangular, hexagonal, square and rectangular geometries, as well as any combination of these geometries. A plurality of frame blocks form a frame of the shutter, each frame block having front and rear faces; a top surface; an outer surface; a vertical inner surface, and a horizontal bottom surface, wherein the bottom surface of a first block of the plurality of frame blocks rests on the top surface of a next lower second block of the plurality of frame blocks and extends inwardly beyond the vertical inner surface of the second block to define a cantilevered portion.
