Take Control of your Colors! Apply your dream shade to natural-colored yarns and fleece. Transform outdated yarns with fresh new colors. Create self-striping and multicolored yarns. It's all possible with Gail Callahan's simple recipes, designed to work in your own kitchen. So, fire up the oven or your slow cooker, clean out an unused microwave, or grab a sturdy kettle - you'll love the results of playing with heat, color and fiber.
