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 20 ball in Ecru contains 20 g with 160 m (175 yd) of double-mercerized thread for glossy, even stitches. Work with a small hook around 1.25 mm and maintain steady tension so the smooth cord shows clearly in heirloom doilies, collars, and trims.
