Build a Mason Jar Solar Patio Lantern.
This Home Made Simple video shows you how to turn a Mason Jar into a solar lamp in minutes, by attaching the solar element from a garden light to the ring piece of the jar lid.
If the solar element is smaller than the ring, wrap it with electrical tape to fill the gap. If your solar element is large enough, you can glue it to the top of the ring with E6000 adhesive.
Twigs removed the plastic shade from the solar lights and sprayed the outside of these jars with Rust-Oleum transparent frosted glass spray paint to give these lights a soft glow.
