If you’ve got lots of scrap yarn from previous projects or old hobbies, the most effective way to get rid of it is to use it in a new project or pattern. However, you don’t have to start a new project — there are lots of other ways to put old or leftover yarn to good use, too. You can use it to practice new techniques, mend clothes, or even to learn a new craft. If you decide you simply want to get rid of it as soon as possible, you can recycle it, give it to charity, or simply throw it away.
