All of our yarn is recycled cotton yarn. Since it is recycled, there is no need to dye the yarn again, which is more beneficial for the environment. We do not dye the yarn because synthetic dye is known to be toxic and harmful. Our company manages each product that is produced and we guarantee at least 95 percent of its original color. The yarn we produce is typically 30 percent polyester and 70 percent cotton. However, we can accommodate any special requests you may have. Thank you!
