    Abstract: A folded structure having utility as the base structure for fanciful novelty structures. The structure is comprised of a base sheet and four outer sheets. The base sheet has eight alternate convex and concave folds. The four convex folds pass through the center of the base sheet and the midpoint of the four sides of the base sheet. Four concave folds pass through the center of the base sheet and through each of the four corners. Four smaller outer sheets are connected to the outer edge of the base sheet. The outer sheets are bisected by convex folds extending outwards from the four respective corners of the base sheet. The resulting structure is a hingeable, flexible, easily-opened structure that can be folded flat making it a useful base for novelty structures.
