Honestly, at first glance I thought the top and bottom borders were the ones that were wrong. Had to go back and carefully read to see that they were the ones that were right. So, I guess either way works. Personally, I would have to change one or the other to make it all match or it would drive me crazy! I'm just too much of a perfectionist. I like the way the side borders make a break between the quilt and the outside border. They both kind of blend into the Flying Geese on the top and bottom borders. Maybe that is how the designer wanted it, but I think your mistake may be a blessing in the long run. I like your mistake!
