"Real" Grass Mats

Comments:

I used 3 of the mats as an entrance runner taped to floor for a superbowl party. It looked great. I used white duct tape between the mats for the yard markings. If put on hard floor it must be taped good in the center of each mat as well as the edges because it is slippery.
The only bad was the mess. There seem to be excessive loose grass. I had to clean the floor just to be able to tape it down.
The product came folded in a box. As soon as I received product I laid flat on floor to reduce the creases before event. Could it be rolled? Or would the shipping cost be prohibtive?
