Use old jeans, cut into squares, add some batting material to the center, sew edges together. Either sew or draw the "X" and "O" onto them and instant tic tac toe game for kids! - Cool to do with beanbags too.
Favorite Part of this is to make a stepping stone path. HOW: cup salt, cup flour, cup (give or take) water. Knead until dough forms. Make impression. Bake at 200 for 3 hours. Do every summer and make a stepping stone path :) What a cute idea!
