👉 Overdyes are a type of yarn that is made from two or more strands of yarn, typically at different lengths. These yarns are often used for making long pieces of clothing such as scarves, hats, and even dresses. The name "overdyes" comes from the fact that they have an extra length or thickness compared to regular yarns. This makes them a bit longer than their standard counterparts, which can be useful in certain situations where you need more material for your project.
