ColourLab Aran is made from a 100% British Wool that has a superb stitch definition and a range of rich deep colours. Wool is wonderful. It is the world's oldest renewable fibre, one of our greatest natural resources and full of natural benefits. Working in partnership with British Wool, we are always assured of responsibly sourced fleece, from the field to our Yorkshire mill. The skilled craftspeople at West Yorkshire Spinners expertly blend and spin British fleece into ColourLab Aran - a warm, breathable and machine washable hand knitting yarn that's perfect for every day. With superb stitch definition, rich and deep colours, and a touch of tweed, ColourLab Aran is a classic yarn for modern lifestyles.
