Vellum Luminaries

Real Simple featured a similar idea in their "New Uses for Old Things" section using parchment paper and decoratively punched holes.

I wanted something a bit sturdier and hopefully longer lasting, so, using vellum, I put together this:

You can buy vellum in 8.5x11 sheets at any craft or printing store.
Print out your message on landscape view.
Adhere the ends together and you're done.  I suggest stapling or some other heat-resistant adhesive.
To make it a little sturdier, I added a rolled up piece of parchment paper cut to size on the inside.

To keep it safe, I use a tiny tea light in a much larger candle-holder.  And there you have it, custom made luminaries!  You can use these for the holidays, birthdays, wedding favors ... imagine making tiny ones with your guests' names and using them instead of placecards at a formal dinner.  Perhaps even print table numbers on them at a wedding.
