A Quilt for Hot Wheels

Oh, my Grandson Zeke LOVES his Hot Wheels, at age 2, they are in his little hands and driving all over.  So when I saw this collection of panels, I was fascinated!  I had often thought of creating a quilt to dive little cars on, but someone else already did it!   There were 5 panels to choose from; I got RACEWAY, AROUND TOWN, and CONSTRUCTION SITE.  There was also a harbor and an airport.  I backed it with flannel (to make it less likely to move around on the floor while playing on it!) and put a thin 100% cotton batting.  The quilting was done diagonally only, about every 6 inches, to decrease unusual bumps along the way.
