A foldable construction incorporates both structural and ornamental qualities into a single form. The construction is made of a single, die-cut, nearly rectangular, blank of flat foldable material which is pre-creased with a unique configuration of fold lines. The completed structure is characterized by a convex dome shape on at least the top side. When folded to create a pair of opposing dome shapes, construction may take the form of a very solid, somewhat spherical, sculpture shape. Each dome is radially sectioned in an equal pattern around the axis of the dome and each section of the dome includes a recess portion which interrupts the outer skin and forms a structural rib. An internal support block may be used between the sets of structural ribs of the opposing domes to provide additional axial support. The resulting construction is extremely strong and it permits the use of paper as a folding material for ornaments which will compete with more sophisticated ornaments in the marketplace which are made of glass, wood or metal.
