Best Homemade Play Dough Recipe

I recently tried a homemade play dough recipe and had so much fun making  it with my kids.  It came out moist and soft and smelled SO GOOD.  You'll need the following:

• 2.5 to 3 cups of all-purpose flour (depending on consistency)
• 2 tbs of vegetable oil (we used canola oil)
• 4 tsp of cream of tartar
• 3/4 cups of salt
• 2 cups of lukewarm water
• Food coloring (we used Watkins Natural Food Coloring)
• 2-3 drops of essential oil (Optional.  We used lavender for purple, peppermint for green etc.  Assist your children with this part as most essential oils are potent and only need very small amount.)
•  Glitter (optional)
