Threading the Singer S0105 Overlock Machine is even easier. The machine features two LED lights, one illuminating the sewing area and the other the thread catch area, ensuring good visibility while threading. With the overlock machine, you can accomplish everything at once: cutting edges, sewing, and finishing. It produces fast and professionally clean seams and finished edges on both stretch and woven fabrics. The machine offers 2, 3, and 4-thread stitches. The selection for the rolled hem is preset on the machine, allowing for clean rolled hems to be made quickly and easily. The differential adjustable thread tension prevents seams from stretching or wavering on stretchy materials and tightens seams on thin woven fabrics. With this overlock machine, you will always achieve a professional finish in your work.
