GÜTERMANN Natural Cotton is a smooth sewing thread for quilters, embroiderers, and everyday stitchers who prefer a natural fibre. Each 100 m (109 yd) spool in Nassau Blue is suited to neat seams and topstitching on many fabrics, from quilting cottons to sturdier wovens. Stitch a small test on scrap fabric to adjust tension, then store the spool clean and dry between projects for consistent results.
