graphed pattern sketches, Nishijin-ori

First drawings of the weave for the textile design are made. In the case of patterned textiles, which are the majority of Nishijin-ori, the design drawings are then copied onto graph paper to make pattern sketches with scaled indications of the individual warps and wefts. Then the pattern sketches are scanned into a pattern data. This used to be done by hand on punch cards. Now, computers do the processing of patterns and the data is stored on floppy disks. When the punch cards or the floppy disks are set into the jacquard loom, they manipulate the raising and lowering of the warps so as to create the pattern.
