I believe that's the Bubble Quilt?
That's from the bubble quit line. That looks HUGE though...You can probably find the smaller ones around in departmental stores.
Try calling NM and Saks and ask them to do a search. Call the 1800 Chanel number to see if there are any left in the boutiques as well.
Yeah, I just looked through the bubble quilt thread in the ref library, and there's a flap similar to that, but not quite the same and not quite as big. It has the leather at the top of the chain handles as well.
Never seen a bubble quilt that huge before!
