ABSTRACT:
A method of making irregular shaped playing discs to achieve proper balance for playing involves the use of a grid (7) divided into quadrants (1, 2, 3, 4) having squares of a predetermined size. A template (8) is placed on the grid (7) into which a desired artwork (9) is fitted. The artwork may include face of a recording star, holiday character or other desired item. The artwork (9) must be placed within the template (8) so that an equal number of squares is taken from each quadrant (1, 2, 3, 4) of the grid (7) within the template (8). Once the shape of the artwork is determined, the recording medium, whether it be audio, visual or a combination of both, is applied. The visual appearance of the artwork (9) may then be silk screened or otherwise applied to the disc. Once the above method is accomplished, the disc can be used as a master for making a mold to premold other discs or each disc may be cut around the perimeter of the artwork to result in discs in the shape of the artwork.
