If you are an initial-level crochet crafter, you would love to work on this crochet cup cozy with a free pattern with all details and written information. For this, you can use Bernat yarn in olive green color. However, it's not essential to use the same color and type of yarn. You can go with whatever you have in your craft store. Moreover, use an 8.00mm crochet hook with a small yarn needle to craft this handmade cozy. yarnspirations
