To achieve optimum results, we cross check yarns ordered from JohnLewis.com to ensure they all carry the same dye lot number. This means that all yarns ordered in a single transaction will come from the same dye lot. Rowan's Original Denim is a cotton mix yarn that is an ideal dupe for denim fabric, with the colour fading over time in a stylish retro effect. Perfect for cable knit sweaters, cardigans and accessories projects for you and the family.
