A method of facilitating visualization and specification of a countertop profile comprises the steps of: i) providing a model of a countertop having a central portion having front and rear edge portions, multiple front portions any one of which may be moved adjacent to a front edge portion of the central portion, and multiple rear portions any one of which may be moved adjacent to the upper rear edge portion of the central portion; ii) selecting a preferred front portion and moving it into alignment with the front edge portion of the central portion; and iii) selecting a preferred rear portion and moving it into alignment with the rear edge portion of the central portion so that a full countertop profile of preferred design is displayed. Most preferably the model comprises a display board having tracks wherein a selected front or rear portion may slide therealong into proper alignment with the central portion. Most preferably the method further comprises the step of designating and identifying the front, central, and rear countertop portions with an alpha numeric character so that a countertop design may be fully specified with an ordered 3 character designation.
