Everyone seems to have a favorite playdough recipe, and many old favorites have been included here. Some require cooking and some don't; some are meant to be eaten and some are not. Choose the recipe that best suits your needs and the ingredients you have on hand. Store playdough in a covered container or Ziploc bag. If it sweats a little, just add more flour. For sensory variety, use playdough warm or cool as well as at room temperature.
