Older #2 white sets have red-colored cams. "YS Star" zigzagger "YS Star" is a brand of Japanese sewing accessories that once included a zigzagger, model YS-7. Like the Singer zigzagger, it fits almost any low-shank sewing machine and draws mechanical power via an arm connected to the machine's needle clamp. Its stitch pattern is controlled by small flat rectangular metal templates, seven of which are included. Two versions were made: White zigzagger The White Sewing Machine Company produced a zigzag attachment like the others. It was called the "White Zigzag Attachment", part number 1640. Rather than using cams or templates, it is much simpler, offering just a single control for adjusting the bight (zigzag width). Sailrite Ultrafeed LSZ-1 In 2000, Sailrite Enterprises, Inc. produced the Sailrite Ultrafeed LSZ-1, a portable zigzag stitch machine for sailmaking. It was created after observing other similar machines such as the Thompson Mini Walker and the Consew 146RB. Blind stitch A blind stitch is a variant geometry of the zigzag stitch. It is also called a "blind hem". It is composed the same way as a zigzag, except that the individual zig-zag pairs are each separated by several straight stitches. Its purpose is to create a nearly invisible hem: because only the zigzags penetrate to the visible side of the material, minimizing their number minimizes their visibility.
