DMC Cordonnet Special is a non-divisible, six-cord cotton thread made for fine crochet, tatting, lace, and decorative edging with crisp definition. This Size 40 ball in White contains 20 g with 233 m (255 yd) of double-mercerized thread for glossy, even stitches. Work with a small hook around 1.0 mm and maintain steady tension so the smooth cord shows clearly in heirloom doilies, collars, and trims.
