Worsted weight yarn is a perfect choice for sweaters, cardigans and pullovers, scarves, cowls, wraps and hats - and homeware too! Knit it on a 4.5 mm. (US 7) to 5 mm. (US 8) needle and it's great for cables and other textured stitches. It is interchangeable with Aran or 10 Ply weight yarn, which is slightly heavier.
