Has anyone else noticed that the heavily pebbled siennas seem to have issues with the whipstitching? I ordered one a while back from Bluefly and returned it because the whipstitching seemed to be coming undone or seperating. I was not sure if it was suppose to look that way but I did not care for it. Now when I see the bag available on eBay they all seem to have the same problem. What is up with that?
