What is melange yarn?
You can dye something with a similar appearance by choosing a yarn of blended cellulose and protein fibers, such as Trekking’s Pro Natura, which is a blend of wool and bamboo. These two fibers take dye at different rates. When dyed with an acid (protein) dye, the wool will take up more dye so it is darker than the bamboo fibers which take up less dye.
