Thanks to its tough nature, denim can still be useful even after it can no longer be worn as clothing. A perfect way to keep on benefiting from denim's durability is by using it to create an oven mitt like this one from My Recycled Bags. They provide a pattern, and a simple shape like this is very easy to sew. You can even recycle old towels for the interior padding—just be sure to use enough to protect your hands when using the mitt.
