Abstract: A method of cutting out pieces which are to be assembled from a length of check fabric 1 in order to obtain continuity or alignment in the design on the fabric at at least some of the assembly points includes the steps of placing a length of fabric on a cutting-out table 2, storing the shapes, positions, and orientations of the pieces to be cut out in a computer memory, with a margin having a width equal to one half of a design element being reserved around some of the pieces in one or two directions, and also storing the positions of points A, B which are to coincide when the pieces are assembled. A pair of images of the fabric, each centered on a corresponding one of the points, are displayed on a screen 8 side by side, and linear and/or angular offsets between the designs are observed, whereafter any offsets are corrected such that the designs correspond in at least one direction.
