WOW!  THESE ARE VERY HIGH QUALITY FOR WALL CLINGS.  I HAVE A ROOM THAT HAS A 30 FT CEILING AND I NEEDED SOMETHING SUBTLE TO FLOW DOWN THE WALL FOR JUST A LITTLE COLOR AND THESE ARE PREFECT.  THEY ARE VERY THICK VINYL AND HAVE HELD UP REALLY WELL SINCE I HAVE HAD TO POSITION THEM, GET OFF THE LADDER, LOOK AT THEM, CLIMB BACK UP THE LADDER, MOVE THEM, AND REPEAT, REPEAT, REPEAT UNTIL THEY WERE PERFECT.  EACH TIME THEY REMOVE EASILY AND STICK RIGHT BACK UP PERFECTLY.  OUTSTANDING!!!!
