With leftover yarn create enough squares to make a checkerboard. Save and clean cat food cans or tuna fish cans (enough for 2 sets of Checkers). Paint cans first with primer. Then paint the cans with a color that contrasts the squares. You can crochet a simple chain to tie the board into a roll and make a simple granny square bag (two large squares sewn together and add two straps) to store your checkers in.
