UNBELIEVABLE!  THE MOUNTING CLIPS WERE ALONG THE WRONG EDGE FOR HORIZONTAL MOUNTING!  THOSE ARE WEEPING WILLOWS, NOT WATER REEDS.  TO HANG IT WITH THESE CLIPS WOULD MEAN HANGING THE PAINTING UPSIDE-DOWN!!!  TOO LATE TO RETURN.  WE DESTROYED THE BOX BEFORE NOTICING THIS !  VERY, VERY DISAPPOINTED IN WAYFAIR.  I HAVE TO PAY A HANDYMAN TO ATTACH CLIPS ON CORRECT SIDE.  HOW COULD YOU MAKE SUCH A MISTAKE??!!!
