This match game is made with 3/4 in square glass tiles from craft store. You can find stickers about that size or maybe a print on craft paper. If using stickers you'll need to stick them on another paper then cut out your squares. Mod Podge (it's a glue you can get most craft stores and walmart) the front of the sticker, place that on the bottom of the tile, let dry. It will look cloudy but that goes away as it drys. These are glass tiles but one dropping on the floor doesn't break, I've tried it. Still try not to drop the box.
If you don't have access to the tiles, use your imagination. I wonder about the backs of poker chips or just chip board. you couldn't see through them but they'd still be cute & work as a game.
