A gradient, multi-colored thread, typically acrylic or a blend, is used to create projects displaying gradually shifting hues. Its long color repeats allow for the development of vibrant, expansive patterns from a single skein. Consider a shawl, where the color transitions smoothly from deep blues to vibrant teals, culminating in soft greens, all originating from one ball of this specialized thread.
This type of yarn simplifies colorwork, offering visually complex results without the need for intricate changes of individual balls. This reduces the number of ends to weave in, saving time and effort. Historically, such gradual color changes were achieved through dyeing techniques or by joining multiple yarn colors, a more labor-intensive process.
