Thanks for the comments.
It's a printed interfacing panel from http://www.quiltsmart.com/khxc/index.php?app=ccp0&ns=prodshow&ref=fun_cellbag.
I don't think you can find that fabric anymore,if you can it's probably limited. It's "Toy Box Designed by Johnny Karwan" I have the marble in red & green and the jacks in red, green & yellow. Now I wish I had bought more because I'm running short. I also made a diaper bag out of it
