I've read in several threads and seen a few pics on how you can tie a knot to shorten the length of Classic Flaps. (see pic below) http://forum.purseblog.com/chanel/large-or-is-it-medium-jumbo-classic-flap-36322-2.html#post746411 I was wondering if this is also possible to do with a reissue?? Being it's just a chain. I mean, since their is no leather, is it possible to make a knot and have it stay. I can see how it would work with the classic flap w/ the leather interlaced in the chain there is some resistance for it to stay put...but what about the "reissue"??? TIA!!
