There are two methods of adding a hanging loop to your crochet potholder. You can crochet a hanging loop for a traditional and simple look or use a wooden ring, scrap leather, or metal grommet for a modern touch. If you want to crochet a hanging loop, here's what you're going to do: 1. Attach yarn to the desired corner of your potholder with a slip stitch. 2. Then, add as many chain stitches as you need according to the desired length of your hook. 3. Once you've reached the end of your chain, attach it to the corner of your potholder with a slip stitch. 4. Weave in the ends, and you're done!
