The Decorative thread guide is a useful tool when serging with thick, strong threads. When overlocking with decorative threads or cords, the lowest thread-tension setting is often still too tight. The special Deco guide changes how the tension is distributed, enabling you to sew with a reduced thread tension. Yarns and decorative threads can be serged neatly and evenly, allowing you to create attractive, professional-style decorations on garments and home furnishings.
