This project was inspired by my mom, because her solution for keeping us out of trouble as kids was to always have something for us to do stashed in her purse. So whether it was a planned wait in an airport terminal, or an unplanned one sitting around a car dealership waiting for auto repairs, she was never caught off-guard. She always had some kind of activity - be it coloring books or a pack of cards - stashed in her big Mary Poppins-esque purse to keep us from getting bored and running around like wild Lord of the Flies children.
On one side is a Checker Board with button game pieces that velcro to the board so they won't fly off and get lost when the board is jostled in your car, on a plane, or bumped by a passer-by in a crowded area. I used adhesive velcro dots, and for additional strength I secured the ones on the fabric checkerboard by stitching a quick free-motion circle along the inside edge.
And in case your kids get tired of Checkers, they can flip it over and play Tic Tac Toe on the other side, using the blue/red buttons for X's/O's.
And as you can see, the final zipped-up version is small enough to easily store in your purse at all times. It's slightly smaller than a standard wallet.
