This rug is beautiful.  If you place it over a wall to wall indoor/outdoor carpet make sure it has a piece of heavy furniture on two sides as it will shift and buckle up when walking on it - yes, I tried the sticky tape (both sides) on all four corners and several other areas but it still shifted and pulled away from the area.  I found out the hard way as we had just laid it and taped it the night before a party.  When guests arrived and walked around it became dangerous.
