Claim:
A method of manufacturing a decorative tile set of decorative tiles for installation adjacent preexisting standard stock tiles, the decorative tiles having opposing upper and lower surfaces bounded by interlocking edges, the method comprising: a. for each decorative tile within the decorative tile set, defining a tile boundary at the upper surface of the decorative tile, wherein the decorative tiles within the decorative tile set are adjacently situated at the tile boundaries; b. providing a bed having an upper bed surface; c. providing atop the bed a workpiece from which the decorative tiles within the decorative tile set are to be cut; d. cutting the workpiece on the bed along tile blank boundaries which are coincident with or outside the tile boundaries, thereby producing tile blanks, the tile blanks having upper surfaces corresponding to the upper surfaces of the decorative tiles; e. cutting: (1) male interlocking structure on selected tile blanks, the male interlocking structure being defined in portions of these selected tile blanks within the tile blank boundaries and outside the tile boundaries, and (2) female interlocking structure on selected tile blanks, the female interlocking structure being defined in portions of these selected tile blanks within their tile blank boundaries and their tile boundaries; wherein the cutting of the interlocking structure on each tile blank conforms the tile blank's upper surface to correspond to the tile boundaries therein.
