A foldable cardboard hook blank formed as a rhombus 14 with fold lines 16, 20, 24 and cuts 22 defining congruent triangle pairs 26, 28, 32. Upon folding the triangles 28 remain in a common plane for attachment to a support surface, the triangles 26 partially overlie each other and also lie in said common plane, and the triangles 32 form the hook body. |
