ABSTRACT:
Master garment patterns are copied while altering the size through the use of a grading device and method of using the same. The grading device has an elongated major axis with parallel spaced indicia therealong, and a pair of minor axes each perpendicular to the major axis with parallel spaced indicia along both. By securing the grading device relative to a copy material, the master pattern is duplicated at an increased or decreased size by moving the pattern along a defined path relative to the device. Movement of the master pattern occurs while maintaining a preselected two dimensional orientation of the pattern respectively parallel to the two dimensional indicia on the device.
