A plaything is formed from a single sheet of material having a first pair of parallel interrupted hinge lines (10 and 11) afforded by spaced hinge portions (10A, 10B, and 11A, 11B), and a second pair of parallel interrupted hinge lines (12, 13) afforded by spaced hinge portions (12A, 12B and 13A, 13B), the second pair of parallel interrupted hinge lines (12, 13) being at right angles to the first pair of parallel interrupted hinge lines (10, 11), and the sheet being so cut as to permit folding of the sheet about each of the hinge lines (10, 11, 12 and 13).
