Creatively sew yarns, cords and wool or felt threads onto your projects with this set of three couching inserts. The inserts fit Adjustable Ruler Foot #72 or #96, and are attached to the underside of the foot. The high-quality materials make the inserts very strong while protecting the surface when quilting with metallic yarns and cords. The hole diameters of 1.4 mm, 1.8 mm and 2.2 mm are suitable for thin, medium and thick cords. Enjoy easy couching using either a plexiglass ruler for guidance or the free-motion technique. Important: the inserts extend the foot an additional 3.5 mm, therefore the height of the foot should be set to the minimum (from 4 mm to 0 mm) prior to installing the foot, so that there is no conflict with the stitch plate.
