It can be used to write a floppy disk that is compatible with the HUS Designer-1Ã??Ã?Â© embroidery machine. You can view embroidery files, even if they are included in zip or rar archives, view thumbnails of files in your working directory, create Designer-1 floppy disks, use any TrueType font [TTFÃ??Ã?Â©] to create monogram lettering, resize, reposition, delete, rotate, and merge sewing patterns, convert from, and save to, various file formats (see chart below) either individually or in batch mode, simulate the real-time stitch out of a pattern, and Change individual thread colors and background.
