DMC Cotton Embroidery Floss in 310 Black is a divisible six-strand thread for hand embroidery, cross-stitch, needlepoint and other needlework. Each 8 m (8.7 yd) pull skein is made from 100% cotton and separates easily so stitchers can vary line weight, coverage and detail. The double-mercerized finish gives the thread a smooth sheen, while colorfast, fade-resistant dyes help finished projects keep their colour through washing and display.
