And the final product:
If you don't like the rustic painted look, as an alternative you can just use a sheer spray paint so that the jars come out looking a lot more clean cut. I was inspired by this article but added a few tweaks of my own to make it more clear and to give the kind of look I wanted. The best part about the lights is that you can just turn them off if you want to at night, otherwise the solar panel just recharges itself during the day. They're great for bedrooms, outdoor decks and patios for that extra DIY touch!
