Enclosed herein is a design and method for creating a durable, compact, collapsible information sheet. This is accomplished by creating a collapsible information sheet comprised of a single elongated loop of a thin strip of spring-like material covered by one or more sheets of flexible covering material. The flexible covering material is comprised of one or more thin layers of fabric, or a synthetic high-density polyethylene fiber, or an alternate material that is durable, light, flexible, preprinted or suitable for printing. The information sheet shape is largely rectangular with slightly rounded corners. The information sheet size is determined by the loop dimension of the spring-like material and the printable covering material encasing the loop created by the spring-like material. The single elongated fabric-covered loop of the information sheet is easily twisted and folded into a compact configuration consisting of a series of smaller concentric loops and covering material layers. The collapsible information sheet may additionally comprise a means for maintaining the compact configuration for storage, such as Velcro closures, snaps or other means later described or obvious to those skilled in the art. When closed, the information sheet is easily opened by twisting the elongated fabric-covered loop of the information sheet. The collapsible information sheet may also comprise one or more removable or fixed accessories such as, but not limited to, a compass or a light to further increase the utility of the information sheet. The collapsible information sheet may also comprise one or more smaller collapsible information sheets that may be temporarily affixed to the perimeter of the larger information sheet.
