DMC Pearl Cotton is a versatile, non-divisible thread that adds clean definition and subtle sheen to handwork, from decorative stitching to visible mending. In size 3 (the thickest), colour 210 is well suited to bold outlines, textured accents, and stitching where you want a smooth twist that stands out. Pearl Cotton comes as a twisted skein, so unwind it before stitching and work in shorter lengths to keep the thread manageable.
