Musing about Villanelles

I have been thinking about writing a villanelle. These poems are powered by two refrains that repeat strategically through the 19 lines. If written well, the refrains echo with new depth and layered meaning with each repetition. What the heck am I talking about? If you are not a traditionalist, you may recognize the form Dylan Thomas' juggernaut classic "Do Not Go Gentle into that Good Night." Notice how the refrains (lines 1 and 3) repeat through the poem and close the final quatrain.

Do not go gentle into that good night,
Old age should burn and rave at close of day;
Rage, rage against the dying of the light.

Though wise men at their end know dark is right,
Because their words had forked no lightning they
Do not go gentle into that good night.

Good men, the last wave by, crying how bright
Their frail deeds might have danced in a green bay,
Rage, rage against the dying of the light.

Wild men who caught and sang the sun in flight,
And learn, too late, they grieved it on its way,
Do not go gentle into that good night.

Grave men, near death, who see with blinding sight
Blind eyes could blaze like meteors and be gay,
Rage, rage against the dying of the light.

And you, my father, there on the sad height,
Curse, bless, me now with your fierce tears, I pray.
Do not go gentle into that good night.
Rage, rage against the dying of the light.

Do you have a favorite villanelle? Feel free to share. Here's a link to one that I admire. Felix Dennis's "White Vase." http://www.poetryarchive.org/poetryarchive/singlePoem.do?poemId=1513
It's a doozy about Adolf Hitler and Eva Braun's last moments.

Have you written a villanelle? The meter tends to be pentameter, but I understand that this is completely up to the author. It seems to me the key is nailing the refrains. Any advice before I give it a try?
