ooh! I love this thread!!! When I was thirteen I made my own version of Arwen's "chase" dress from the FOTR movie. The next year a made a crack at her "bridge" dress from the same film. I love sewing!!! Sadly, I haven't had time to do another costume. I would love to invent my own elvish costumes.
www.alleycatscratch.com/lotr is a great reference site. It helped me bunches. Actually, I have my second costume posted in the Elven part of their scrapbook. If you want to see some cool costumes, that is the place to look.
