Before throwing out that tomato sauce jar, consider all that it can do if its lid is switched out. Worry not, this is not DIY. It's ready-to-buy. My favorite reuse revamp is the solar lid light in Photo 3. This solar lid automatically turns on when it gets dark, is water resistant, and fits any jar that takes a standard mason jar lid. Eco-friendly and good-looking, these products are hard not to like. And the other lids are just as great.
