We haven't been able to lay our beautiful rug yet.  It was delivered late, following a heavy snowfall.  When we unrolled it, it had huge creases from folds that probably were frozen (sitting in storage somewhere awaiting delivery).  The rug wouldn't lay flat, so we have rolled it up in the opposite direction and are going to wait a few weeks to see if these creases will smooth out.  Returning it will be difficult--it's a thick, heavy rug.  We're senior citizens (73 and 81).  We'll wait and see what happens.  An exchange may be necessary.
