Pearl Cotton size 3 is the perfect thread for needlepoint, creative stitchery and embroidery, plus it works well on plastic canvas. DMC Pearl Cotton is a highly mercerized, non-divisible, lustrous 100% cotton thread on a twisted skein. The twist of the thread is how it received its “Pearl” description. The thread is soft, silky, does not fluff or kink, and 100% colourfast.
