I made a few of these - little (10 to 15cm tall) mason jars with the solar light built into them.

They were fun to make.

I put a light coat of spray paint on the inside of the jar, to soften, diffuse the light.

I also substituted fake, plastic "flickering" candles for the solar lights, in the jars.

That's a good effect, too.

As I discovered, life probably would have been easier if I'd spray painted the outside of the jar then scratched a design onto it, but I didn't think of that, so I did things the hard way.

So many ideas...
