A decoration in a variety of shapes and including a substantially flat main body and a string. The main body has a plurality of extensions extending from a base portion. Each extension has an aperture therethrough at its free end. The string passes through each aperture in a same direction. The extensions are foldable such that the ends with the apertures are stacked and the string passes through the apertures in a line. Accordingly, the decoration forms a curved surface. Two edges of the main body can be attached to form a closed loop structure. The extensions may extend from both ends of the base portion to form fully enclosed surfaces, for example a sphere.
