DMC Pearl Cotton Size 8 is a smooth, tightly twisted thread ball for fine embroidery, hardanger, and crochet edging. Each ball contains 80 m (87 yd) of highly mercerized, non-divisible 100% cotton with a lustrous finish that resists tangles and fraying. Use colour 640 to add clean definition on cotton, linen, or canvas; stitches stay vivid after washing when cared for with your fabric's guidelines.
