Abstract: A paper assembly is formed having an envelope and a carrier portion, such that the overall assembly is a generally flat paper assembly having a length and width of a standard paper size such as 8½ in.×11 in. or A-4 size. The assembly, having a footprint equal to a standard paper size, may be fed into a standard size paper tray of a printer such as a laser printer or an ink jet printer, with the printer printing on the front face of the envelop. After printing the envelope may be stuffed with material to be mailed, and the envelope separated from the carrier portion and sealed for mailing. In a first embodiment the carrier is an L-shaped piece of paper that is formed separately from the envelope and releasably adhered to the backside thereof, the L-cut having an acute angle and a rounded corner. In another embodiment the L-shaped carrier is releasably adhered to the front side of the envelope.

Abstract: Title areas are preprinted on the table-of-contents sheet and oriented so that the titles are designed by the user on his personal computer and printed in the areas on his desktop printer. In addition to this sheet a set of dividers having staggered tabs are provided to the user in the retail packaging. The tabs have individual indicia (such as coloring, numbers and/or letters) corresponding to that of each of the title areas. The divider sheets when in a binder system have the tabs and their indicia running in a landscape direction from left to right. Lines on the sheet connecting the title areas with the corresponding tabs can be provided.

Abstract: Generally speaking, a method for forming custom-printed, three dimensional structures using a computer and a computer-controlled printer, has several steps. A flexible rectangular sheet is perforated to form a removable portion. Lines of weakness are formed on the removable portion, to serve as fold lines that ultimately folding the two-dimensional removable portion into a three-dimensional structure. A user instructs a computer program to command a computer-controlled printer to print particular information onto the printing surface of said removable portion. After printing, the user removes the removable portion from the sheet along the perforations and then folds the removable portion along the lines of weakness and secures the folded sheet into a three dimensional structure. The removable portion may be provided with a pressure-sensitive, water-activated, cohesive or other type of adhesive for adhering securing the folded sheet into the three-dimensional structure.
