Simply ideal for "invisible" quilting or applique'. Can be used for hand or machine sewing. Soft, strong, fine, and smooth. The best option for "stitch-in-the-ditch" and for outlining appliqu�© shapes. Disappears when quilted or sewn into light-colored fabrics. For overall best sewing results, use a cotton bobbin in conjunction with Essence nylon monofilament top thread. Less shiny, wiry, and lower (stretch) elongation than polyester monofilament.
