It is completely normal for your rug to create creases during shipping. Just lay your rug flat, it will need some time to relax after it is unfolded. Any creases will come out after a few days of laying flat and your rug will go back to its natural state. You can help speed up the process by applying heavy weight on your rug. Some ideas: use books, magazines, an upside-down table, another rug or heavy blanket. These all work. Or just leave it be, it will flatten down by itself in due time.
