Canvas Checkerboard

Kids who learn how to play checkers will always have something to do on a rainy day. Making a portable checkerboard ensures they can play almost anywhere. Collect bottle caps in opposing colors (you'll need 12 for each side), or use tempera or acrylic paints to paint the tops of mismatched caps with a color of your choice. Bottle caps stack easily, making for very regal kings.
