A sturdy 6-ply thread, Dazzle™ is comparable in weight to a #8 perle cotton. This 100% rayon and metallic mix carries a naturally bright luster with a silky finish, making it an excellent choice for crafts, crochet, knitting, and highlighting the details on dimensional stitches. Because of Dazzle's™ light-reflective properties and "pop" of metallic, the detail on wool applique? and layering can be enhanced with edging stitches for that extra sparkle. From Wonderfil Speciality Threads. This is a 200 yard spool.
