Abstract: A locking mechanism is provided for a pop-up greeting card. The card includes first and second generally planar panels which are connected to each other at a fold line. A plurality of pop-up elements extend from the inner surface of the first panel to the inner surface of the second panel. The card includes a locking mechanism having a pivoting tab which can engage a stop member, maintaining the card in an open position. Selecting the appropriate length of the tab determines the angle that the card can be opened. The stop mechanism can be located on either the first or second panels or on one of the panels and a pop-up element.

Abstract: A generally planar ornamental structure is formed by dividing a large common panel into subpanels at fold lines, and cutting individual lines through each of the subpanels. The subpanels are then folded on each other in an accordion-like structure to form overlapping subpanels, providing a desired design configuration. This can be used to form, for example, an ornamental box lid, a greeting card or a portion of a book, such as a child's book.
