Rico Essentials Cotton is a 100% mercerised cotton yarn that is understandably popular. The mercerisation process gives this cotton a lustrous sheen, making it a lovely fine and smooth yarn with excellent stitch definition. Compared to many other cottons, Rico Essentials Cotton is wonderfully light, making it far more pleasant to work with on warm days. In a generous selection of colours, you're sure to find what you need - why not mix and match to find the perfect blend of colours?
