Homemade Playdough Recipes
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.
Oatmeal Playdough
Materials
1 part flour
1 part water
2 parts oatmeal
Bowl
Directions
Combine all ingredients in a bowl; mix well and knead until smooth.
This playdough is not intended to be eaten, but it will not hurt a child who decides to taste it.
Store covered in refrigerator.
Your child can make this playdough without help; however, it doesn't last as long as cooked playdough.
