At a local antique mall, the Moorhead Antique Mall, I spotted another idea for salvaging vintage china pieces: turning tea cup saucers into nightlights.
I’ve also seen old cups (with and without saucers) turned into night lights (or night lamps), like this one by micah7:
But I think that since the vertical saucers are flatter and nearer to the wall, they are less likely to be damaged by an inattentive person vacuuming. (But maybe that’s just a problem at my house?)
I’ve never tried making night lights from china pieces, but if you want to give it a try, here are a few helpful “how to” links:

Also, your local hardware store may offer cutting services for a fee.
