Has anyone ever made a backpacking quilt from a down bed quilt? I'd like to give it a try as they can be had inexpensively on ebay... people might have them lying around in fact. Usually they have cotton covers and so would have to be covered with nylon.

Do you think the cotton cover would add too much weight? And of course you could shape the original down quilt to basically be a core for the top by running a double row of stitching then cutting between them (this would keep the down from leaking all over the room when you had to cut the original quilt).

Very interested in making my own gear and I have very good sewing skills... I need to be braver so many people on here it's their first time sewing and they jump right in!
