I want to make one too. I have only been married so I am not ready to cut my own dress up yet. So I bought a wedding dress on craigslist for 50 bucks and have slowly been cutting away at it. I fanned out the beaded part of the train and left it as one piece. I also bought some black tux like fabric. i haven't gotten much further than that. I want to go with a simpler pattern. The other colors I had in my wedding were champagne dresses and red roses. So I might add some red and/or champagne. I can't decide if I want to add some more of the funky fabrics or add some cottons.
You have any plans? I would leave some of the prettiest parts cut out in just big pieces. Like the train of boddice or what have you. I wanted to leave one piece so you could still tell that it comes from a dress. You should take some pics. let us see what you have! Good luck. It took me several days to make the cut on a dress that wasn't mine. That first cut is a biggie. :)
