The idea isn't from me, I found it on the site of Atelier Bep. On the blog of Monique you can find a very good instruction with pictures.
For mine, I used a charmpack of Nancy Halvorson, Marne sent me this a few weeks ago. Charmpacks are very handy, you just start and don't need any cutting ; ). I put a glass in it with a little candle, and now it's on my dining table.
