I decided to look to Zibbet for inspiration regarding re-using vintage items, and I wasn't disappointed. I came across as store named ScreamingMonkey Circus, and it's tag-line is that it makes old technology new again. Of course I had to check out the items.
The store isn't that full, but I noticed the ball jars to the left. They're Mason Jar Lanterns, and you use them outdoors; whether you want a winding path or garden lit, they would be ideal. You want light, you pop the battery in, when you're done, take them out. The would also work well for a garden party or wedding. I can also seen them working great for Halloween, and lighting paths for trick-or-treaters.
I've seen Mason Jars in a variety of colors, so you could mix and match. Vintage lids and bands are used, they are 30 plus according to the listing, so it truly is re-using. It's a creative idea, and I think they're pretty. I just wish I had thought of it.
