I like the rug but it was folded in order to ship. That created huge creases and raised areas. We vacuumed, turned it upside down to see if it would relax after 2 days I called and the suggestion was made to iron the rug.  I liked the rug so I covered sections with an old pillow case and ironed it from the back.  Then turned it over, vacuumed, let it rest for a day. Still very large creased areas and raised sections. I used my old pillowcase between the iron and steamed the carpet and used a section of plywood to lay on areas to keep it flattened until it cooled. That helped but required I do it twice to get it flat.  Good thing I liked the rug.
