We went to a light display at the Missouri Botanical Gardens over the Christmas season. One area that really struck me as beautiful was a large tree with about 20-25 lanterns hanging in the branches. I thought that would be a neat thing for the lake lot. I found the exact lanterns they used, but at $25 a piece they were out of the question. Plus they run on batteries, and that would be a PITA. Obviously, solar is the way to go.
I had the idea to use mason jars instead of lanterns, and to use cheap solar walkway lights. I think the finished product look pretty cool.
Making them is super easy. I made 10 in about an hour. You can see the step-by-step on my blog: Bigger in Real Life: Jar Lights
I'll make simple twine hangers to hang them in the trees. I'll post up more pictures when I get them hung up at our lot.
