DMC Cordonnet Special is a non-divisible crochet thread designed for heirloom lace, borders, and fine decorative edgings on linens or garments. This size 100 ball is 20 g and 366 m (400 yd) in Ecru, spun from 100% cotton with a firm 6-cord twist for clean stitch definition. The double-mercerized finish adds a smooth sheen and helps resist splitting when stitching with small steel hooks such as ¾ mm.
