It glows! At first glance, this may seem like ordinary white yarn, but don’t be deceived! When darkness falls, DIY Glow yarn shines bright. Made from 100% polyester in a classic worsted weight/CYC 4, it’s ideal for fibre crafters of all ages and skill levels. Create glow-in-the-dark hats, scarves, and cowls for evening outings, or add playful trims to costumes.
