We see these sorts of beautiful creative reuse lamp ideas all the time, but we never consider the fact that we might be able to make them ourselves at home. We love this project (because we love mason jars), and we think we could actually pull it off.
These mason jar lights are posted over at Design*Sponge with some really easy-to-follow instructions.
Put the lights together with just a few materials (and in just a few steps) and then give your favorite electrician a call to actually do the installation.
If you have a few vintage mason jars on hand this project should be a snap. If you don't, they're easy to find at flea markets or thrift stores.
