Check out this awesome fabric I just bought from etsy seller SewTogether.
It includes 2 squares each of 50 different I Spy fabrics. I plan to make two matching quilts - one for Pinky and one for Chaos. I Spy is one of Pinky's favorite games. My thought is that if I make 2 quilts Pinky and Chaos can play I Spy together - each asking the other to find something on their quilt. I do plan to put the squares in a different order on each quilt to make it a bit harder.
The finished size on these will be less than 2 feet square so they should make for a great travel or diaper bag game!
