I absolutely love the pattern and colors in this rug! As we unrolled it there were 4 creases that extended from one side to the other from being rolled up.  I figured that they would flatten out in a day or two.  Well, it has been two weeks and they are still there, and don't appear to have flattened out at all. Obviously, I am going to have to try placing heavy furniture or something on the creases and hope that works!
