I had bought a beautiful giclee from Wayfair to put in my great room.  Was so thrilled with it that I purchased two sets of the butterflies in brass to complement the picture.  Together they just make the room complete.  Suggestions:  1. arrange the butterflies on the floor to get an idea of how you want the wall to look.  Out of the total of 18 butterflies, I used 15 as my wall is rather large.  2. Don't pull off the strip on the back of the butterflies until you are absolutely certain how you want it to hang as you might pull off the wall paint if you try to re-position.  Thanks again Wayfair for providing your customers with the best of everything for our home decor needs.
