Stumpwork designs, like any other design in your embroidery software, are saved to native ART file format. The ART format contains a complete set of design information in a single ‘all-in-one’ file – object outlines and properties, actual stitches and machine functions, thread colors, a picture icon and comments. It also includes all stumpwork elements in addition to the base design. When it comes time to output the design, however, it is necessary to create separate machine files for the machine.
