GÜTERMANN Metallic is a machine-embroidery thread made to add a reflective accent to ornamental stitches and decorative seams. Colour 41 comes on a 200 m (about 220 yd) spool and is intended for decorative machine stitching, quilting highlights, and embellishment on many fabrics. Choose a metallic machine-embroidery needle in the 80–90 range and test stitch settings before starting your final piece.
