The only one I know of is http://www.sleepingbaby.net/jan/Baby/
You could check www.thebabywearer.com too for other options.
My favorite wrap by far is the Wrap'n Wear. You can get a dvd from them that has 12 hold on it. It is a very light weight woven wrap. So it is not too strechy. I do not like the one made out of a jersey because one your baby gets big you cannot use it.
As for making one I can tell you how to do it if you want. Just let me know your dress size and i will tell you how long it should be.
