ABSTRACT:
A writing pad containing a stack of horizontally aligned sheets, each of which is cut to the same size and shape. Initially, the sheets are stacked so that the corner edges of the stack are perpendicularly aligned with the top and bottom sheets. Preferably, the sheets in the stack are assembled in sets wherein each set is provided with a specific border color or colors which differ from the color or colors used in the other sets. The sheets are then fanned or swirled uniformly as to form helical flutes extending between the top and bottom sheet of the stack. An adhesive is applied to one side face of the stack to hold the stack in a swirled configuration. The top and bottom surfaces of each sheet are provided with a printed border that frames the writing area. By varying the colors printed on the different sets, a wide variety of visual effects can be obtained.
