The tutorial is here - it's very straightforward, though. The pockets at the bottom hold cars, the 'road' flips up for play and down over the cars to be rolled up for travel. Perfect for waits at the Doctor's office, going to Grandma's house, etc. I hope they love them!
Here is it rolled up and tied, It has about 4 cars in it so it's pretty bumpy :-)
And here it is opened up. The road flips up and is perfect for a little playtime with the cars.
