Vintage dairy cream separator funnels have a great industrial look — and a great primitive look when rusty.
They make great candle stick holders!
If you plan on lighting the candles, you should place them on an appropriate heat resistant/fire-safe container — antique saucers and plates work well for this and you can even mix and match leftover saucers or find a use for those in not-so-great condition. You might even want to weave some lace or ribbon in the holes to play up the textures against the old metal. …And if you are using ribbons and things, why not add some vintage buttons too? There are lots of possibilities.
